Why read this? : Marketers often forget about the importance of colour in design. We share how designers think about colour, and apply that to key marketing objectives. Learn how to use colour at different stages of the brand choice funnel for example. And how to use it to boost your brand identity and reinforce your brand values. Read this to learn when, where are how to use colour in design to boost your marketing impact.

It’s cold and and dark in Sydney right now. So to boost everyone’s mood, we bring a bit of colour to the blog this week. 

We’ve covered specific uses of colour in previous articles. For example, using colour psychology and choosing a colour palette when creating a new brand. 

But this week, we go broader. We review the basic terms used to describe colour so you can talk about them with designers. And we look at key marketing activities where knowing how to use colour can improve how you do marketing.

Let’s start with why colour is such a core component of design work. And why it matters so much.

Why colour in design matters

Along with typography and composition, colour is used in design because colours are a way to easily show meaning. 

The average person can distinguish between 10 million different colours, and we associate specific colours with certain meanings. 

It’s this ability to associate meanings with colours and distinguish between them which designers tap into when they use colour in design. Good use of colour grabs people’s attention, makes designs more engaging, and can influence behaviours. 

Attention, engagement and influencing customers. Sound familiar, right? Because these are often your marketing objectives. So, using colour in design helps deliver your objectives. 

These colour associations act as short-cuts and signals for our brains. We don’t have to re-assess colours every time we see them, if they deliver a consistent meaning.

For example, think about traffic lights.

We don’t pause each time we get to a traffic light and wonder what each colour means.

We already know. Our brains have learned to associate meanings with each colour.

Red stop. Amber warning. Green go. 

Even more interesting is those same colour associations work in different contexts.

You see them in business reports and performance dashboards. You see them in health apps and in nutrition panels on food packaging. 

Rather than have to explain the meaning in words, the colour associations do the explaining for you.

This is why colour in design matters so much and why marketers should learn about it.  Colours make the communication of meaning easier, faster and more memorable. Your marketing has to have meaning to work. Colours help you deliver that meaning.

Colours can help identify categories

For example, colour is often used as a short-cut to identify categories, particularly on packaging and in-store signage. 

Go to the fruit and veg section of the supermarket. You expect to see a lot of greens, reds and yellows. Go down the milk aisle. It’s all white, with mostly green and blue labels. 

These colour associations help customers orient themselves quickly so they can navigate to the right aisle. It’s an easy and convenient short-cut for customers to find what they need.

If you’re launching a new product into a category with strong colour associations, you need to factor those association into your packaging design. You need to  make it easy for customers to know which category your new (and to them unfamiliar) product is part of.

Here’s the challenge though. Because if every product in the category uses the same colour palette, how are customers meant to differentiate between them?

Take bottled water for example. 

The product packaging between different brands all looks very similar. You can see it in this screengrab from Coles online. Similar bottle shapes. And colour-wise, clear blue bottles and simple blue and / or red labels across the board. The colour only changes if the product is flavoured (e.g. the lemon infused water).

In fact, the one which stands out here is Voss.

It has an unusual bottle shape. And it chooses to use a neutral colour palette, rejecting the use of the standard bottled water category colour cues of blue and red.

It stands out because it’s different. And stand-out is something you want when it comes to colour in design. Choosing a colour that’s different from what’s around you gets you noticed.

Brands need to be different to stand out

Picking a different or unusual colour helps your brand stand out more.

This stand-out comes from a psychological bias called the Von Restorff effect. It’s based on evidence that we notice things that are different, more than those that are the same. (Read more about this bias in our review of the book Choice Factory).

If we write 1,2,3,4,E,6,7, you notice the letter first, right? Why?

Because it’s different.

If we see a bunch of similarly packaged objects (like all those bottled waters), we notice the most different one first. 

Combine category identifiers and the Von Restorff effect, and it’s clear marketers need to think carefully about how to use colour in the design of their marketing. 

You want to be similar enough to the category colour that customers recognise you belong to the category. But you need to be different enough that you stand out from competitors and get noticed. 

To talk about colours with designers, marketers should know the basic language of using colours in design.

The language of using colours in design

Remember those 10 million colours we mentioned? How are you going to describe them? You might say something’s blue. But is it navy blue, sky blue or denim blue?

Thankfully, the design world has created a set of terms and systems to make sure colours are described and reproduced consistently.

For example, hues, tones and saturation are common terms used for colour in design :-

  • Hues – the generic name of colours e.g. red, yellow, blue
  • Tones – the amount of light (tint) and dark (shade) that sits within colours
  • Saturation – the intensity or chrome of the colour, which can be full or low and relates to the amount of grey used in the colour. 

Hues are the start point in colour design. Adjusting tone and saturation (among other factors) changes the hue to give you millions of variation in colour. These variations are then labelled based on the most relevant colour identification system.

Colour identification systems

There are 5 main colour identification systems. (see our guide to colour in marketing for detailed descriptions). Which one you choose usually depends on whether the colours appear on a screen, or are being printed on physical materials. 

Colours on screen

For colours on a screen, the choice is between the RGB system and the Hex system. These work by combining different light colour sources to make a single new colour. The main difference is how they label the colours.

Colour identification systems - RGB, Hex, HSB and CMYK that you need to know to use colour in marketing

The RGB system gives a value from 0 to 255 to the Red, Green and Blue colour mix for each colour. How these 3 colours combine based on these values “makes” a new colour. The RGB label is listed as a value for each of the R-Red, G-Green and B-Blue values.

So, the primary colour red would be all red, and no green or blue. (It would be labelled R255, G0, B0). But add green and blue to that colour (say R255, G125, B125) and the colour changes from red to a strong pink. 

Mixing the RGB colours gives you different colour mixes. Mixing all the RGB colours together in full “creates” the colour white. (R255, G255, B255)

The Hex system on the other hand labels each colour with a 6 character code. (So for example, #A321621 is the Hex reference for the Ruby Red colour we use on this site).

RGB labelling makes it easier to understand the colour mix of a specific colour. But it’s a more complex labelling system.

Hex labelling is most often used in website design, since it describes the colour with only the minimum amount of information.

Printed colours

For colours used on print materials, the colour identification system needs to work differently. There’s no light source with print. The colour is based on combining ink colours. 

The most common is the CYMK system, which gives a score of 0 to 100 for Cyan, Yellow, Magenta and Black. This works the opposite way to on-screen colours as adding colours together moves them towards black rather than towards white. The colours are subtractive. Full CYMK (C100, M100, Y100, K100) is completely black. 

There 2 further system options for print. HSB – Hue, Saturation, Brightness – and Pantone colours – which are mostly used with certain types of print specialisms such as packaging development

Designers should know each of these colour systems, and use the most relevant one based on the context.

Marketers don’t need to know the full details of each system. But they should know there are different systems and the right system helps make sure colours in design are used consistently. 

Work with multiple colours in combination

Designers use colour to improve legibility, contrast and harmony in designs.

These factors become even more important when working with ranges of colours. How colours combine together can make a big difference to the impact of a design. Colours need to “go” well together.

Done well, colour combinations make designs clear and feel more balanced. Done badly, the effect can be jarring and off-putting. 

As per our guide to colour in marketing, you have many options when it comes to combining colours :-

  • Analogous – colours that sit next to each other on the colour wheel.
  • Complementary / Split Complementary – colours that sit opposite each other on the colour wheel
  • Triads – Colours that split in three equal directions across the colour wheel
  • Monochromatic – One signature hue, but with progressive changes in Saturation and Brightness

The colour combinations you use influence how colour in your design works. You can use different colours to do different jobs and convey different meanings. (see for example our guide to how we chose our colour palette).

You might use strong warm colours to grab attention for example. And complementary cooler colours when you need to be more conversational and soothing in your design. 

Using colour in design for marketing

When discussing colour in design for marketing, start with the business and marketing objectives. Knowing what you’re trying to achieve helps you make better colour choices.

Marketing objectives often relate to key stages in the brand choice funnel. As per our marketing planning guide, the funnel identifies different stages of the customer’s buying process. 

There’s different marketing and design challenges at each stage. The role and choice of colour in your designs will differ depending on the stage. 

The brand choice funnel - trust - aware - consider - trial - loyalty - repeat purchase

Use colour in design for awareness

For example, when you have an awareness challenge, you can use colour as a way to stand out and be more distinctive(Remember the Von Restorff effect we mentioned earlier).

In the book of the same name, marketing influencer Seth Godin calls this the “Purple Cow” approach.

He uses the example of Milka, the Swiss chocolate company. In the book, he describes how they used an unusual colour (purple) on something directly related to their product (a cow) to help them stand out. Obviously, cows aren’t normally purple. So, you as a potential customer tend to notice a purple cow because it’s different. It stands out. 

It’s a simple thing, but it’s remarkable enough to stand out. See a Purple Cow, and you think of Milka chocolate. You use unusual or provocative colours in your designs if the marketing challenge is to drive brand awareness.

Use colour in design for consideration and trial

Beyond pure awareness, colour also plays a role in consideration and trial. But it’s a more subtle role. It often works in conjunction with other decision factors.

You need market research to understand how much influence it has.

For some categories, colour plays a direct role in the purchase decision  – cars, fashion and home decorations for example. You need to understand what impact colours have on buying decisions for these types of products. 

In other categories, colour plays a more subtle role. 

For example, colour can be used to set a mood and temperature for the design. Certain colours have strong associations with certain moods and temperatures.

Warm colours (red, yellow, orange) are associated with energy. If you want to evoke feelings of fun (e.g children’s toys), excitement (e.g. Mexican restaurants) or passion (e.g. romantic getaways), warm colours in your designs help reinforce energetic moods and temperatures.

On the other hand, cool colours (blue, green) are associated with calming and measured feelings. If you want to evoke feelings of trust (e.g. banking), expertise (e.g. medicines) or relaxation (e.g. natural beauty products) then these cooler colours reinforce those types of perception.

Use colour in design to reinforce brand identity and values

So, you can use colours to reinforce desired messages and positions at different stages of the brand choice funnel. But you can also use them to help identify your brand and reinforce its values. 

To do this, you need to create a colour palette that’s appropriate for your desired brand identity. Then use it repeatedly across all your brand activation. The more repetition, the stronger the connection customers will make between those colours and your brand.

These brand colours become a tangible brand asset within your brand identity. They should be consistent with and reinforce your essence, values and brand personality.

So for example, some brands like MacDonalds and Coca-Cola are very energetic and extrovert. They encourage sociability and warmth. 

Warm colours like red and yellow sit better with those attributes. Look at the colours those brands choose. They’re all from the warm end of the spectrum. 

They use those colours consistently. Even if you just saw the colours and nothing else, you’d still easily recognise the brand. 

That’s why the Yellow and Red MacDonald’s arches catches your eye as you’re driving along. And why you notice the Red coke sign when you’re thirsty.

But compare that energy with brands who choose colours from the cooler end of the spectrum. These brands typically have identities that are much more low-key and calm. They’re more introverted.

This suits more professional oriented brands like LinkedIn for example. Or brand that encourage quiet relaxation like Starbucks.

Cooler colours like blue and green reinforce perceptions of calmness, professionalism and relaxation. Those are the colour psychology associations people have with those colours.

Apply colour consistently through your brand activation

Once you’ve chosen your brand colour palette, you need to use it consistently. Make sure agencies and suppliers (e.g. packaging printers) use it consistently too.

It’s usually easier to maintain consistent of colour when it’s used on screens. Once it’s coded into the system, it doesn’t change on the screen.

It’s harder to be consistent with printed materials. Depending on the print materials, colours can look slightly different. This affects marketing materials like packaging and sales promotion materials like Point of Sale displays and brochures. 

You, or your designer should have a good relationship with your printer. Consistent colour printing on materials requires a high level of skill. Skilful printers help you maintain colour consistency across different types of printed materials.

Good colour consistency helps customers more easily recognise your brand, and remember it. Both of those are clearly good things to improve the design impact of your marketing activities.

Conclusion - Colour in design

Colour plays an important role in our lives. It creates meaning. Those meanings help us create mental short-cuts to make our lives easier. 

You can use these colour meanings to boost the impact of your designs and marketing.

Choosing the right colour in design grabs attention. The right colour choice can drive engagement and influence buying decisions.

These colour in design choices help you deliver your marketing objectives.

Make colour choices at different stages of the brand choice funnel. Colour helps reinforce your brand identity and brand values.

Use colour to help your brand stand out and be remembered. Use it to help organise information and key messages you want to land with customers.

In fact, when you use it well, you’ll make competitors green with envy. And you increases the chances of your finances moving out of the red and into the black. You definitely won’t end up feeling blue.
