Understanding the Colour Wheel: A Simple Guide to Using Colour in Your Designs

Understanding the Colour Wheel: A Simple Guide to Using Colour in Your Designs

Have you ever chosen two colours that you thought would look amazing together, only to put them into your design and wonder why something just doesn't feel right?

This is where the colour wheel can become one of your most useful design tools.

You don't need to be a professional graphic designer or understand complicated colour theory to use it. Once you know a few simple principles, the colour wheel can help you create designs that feel more balanced, coordinated and intentional.

So, let's make colour theory simple.

What Is the Colour Wheel?

The colour wheel is a visual way of showing how colours relate to one another.

At its simplest, it begins with three primary colours:

🔴 Red
🔵 Blue
🟡 Yellow

These are traditionally considered the starting colours because they can be combined to create other colours.

Mixing two primary colours gives us the secondary colours:

🟠 Red + Yellow = Orange
🟢 Yellow + Blue = Green
🟣 Blue + Red = Purple

Between these sit tertiary colours, created by mixing a primary colour with a neighbouring secondary colour.

Together, they create the familiar colour wheel.

But the really useful part isn't memorising the names — it's learning how to use their positions on the wheel when you're designing.

1. Complementary Colours — Perfect for Contrast

Complementary colours sit opposite each other on the colour wheel.

Examples include:

💙 Blue + Orange
💜 Purple + Yellow
❤️ Red + Green

Because they're so different, they naturally create contrast.

This can be brilliant when you want something in your design to stand out.

For example, if your design is mainly blue, a small amount of orange can immediately draw attention to an important element.

Great for:

  • Call-to-action buttons

  • Headlines

  • Invitations

  • Posters

  • Social media graphics

  • Designs that need a little pop

Design tip: Complementary colours can become overwhelming when they're used equally. Try choosing one as your main colour and using the other as an accent.

2. Analogous Colours — Easy, Coordinated Palettes

Analogous colours sit next to each other on the colour wheel.

For example:

💙 Blue + Blue-Green + Green

or

❤️ Red + Red-Orange + Orange

Because these colours are closely related, they naturally work beautifully together.

If you're struggling to build a colour palette, this is one of the easiest places to start.

Great for:

  • Seamless patterns

  • Digital papers

  • Stationery

  • Branding

  • Children's designs

  • Coordinating product collections

Choose one colour as your main shade, another as your supporting colour and the third for smaller details.

Instant palette!

3. Monochromatic — One Colour, Lots of Possibilities

A monochromatic palette uses different shades, tints and tones of one colour.

Imagine starting with dusty pink and then adding:

🌸 Pale blush
🌸 Soft pink
🌸 Dusty rose
🌸 Deep berry

They're all related, so the finished design feels beautifully coordinated without looking completely flat.

This can be particularly useful when creating elegant, minimal or sophisticated designs.

And monochromatic doesn't have to mean boring!

Different depths of the same colour can create plenty of interest.

4. Triadic Colours — Colourful but Balanced

A triadic palette uses three colours spaced evenly around the colour wheel.

A classic example would be:

❤️ Red
💛 Yellow
💙 Blue

This creates a much more colourful palette while still maintaining balance.

The trick is not to give every colour equal importance.

Try something like:

60% main colour
30% secondary colour
10% accent colour

That little 60-30-10 rule can make choosing how much of each colour to use much easier.

Warm Colours vs Cool Colours

Another useful way to think about colour is whether it feels warm or cool.

Warm colours 🔥

Reds, oranges and yellows tend to feel:

  • Energetic

  • Cheerful

  • Cosy

  • Exciting

  • Welcoming

Cool colours ❄️

Blues, greens and many purples can feel:

  • Calm

  • Peaceful

  • Fresh

  • Relaxing

  • Professional

Neither is better than the other.

It's about asking:

How do I want someone to feel when they look at this design?

That question can completely change the way you choose your colours.

Don't Forget Neutrals

Not every part of your design needs to be colourful.

Cream, white, beige, grey, brown and black can give brighter colours room to breathe.

For example, instead of combining five strong colours, you might choose:

🌸 Dusty pink
🍷 Burgundy
✨ Muted gold
🤍 Warm cream

The cream acts almost like a resting place for the eye and allows the stronger colours to become the stars of the design.

Colour Is About More Than the Colour Wheel

Here's something important to remember:

Colours can technically work together according to colour theory and still not look quite right in your design.

Why?

Because you also need to consider:

Saturation

How bright or muted is the colour?

A bright cherry red will create a completely different feeling from a muted burgundy.

Value

How light or dark is the colour?

Using different values helps create contrast and prevents everything from blending together.

Temperature

Even individual colours can lean warmer or cooler.

You can have a warm pink with peachy undertones or a cooler pink that leans towards purple.

These little differences can completely change a palette.

An Easy Way to Build Your Own Colour Palette

Next time you're starting a design, try this:

Step 1: Choose one colour you absolutely love.

Step 2: Decide how you want the design to feel — playful, elegant, cosy, bold, calm, festive?

Step 3: Use the colour wheel to choose complementary, analogous or monochromatic colours.

Step 4: Add one or two neutral shades.

Step 5: Choose one colour to use sparingly as your accent.

Step 6: Test the palette on your actual design.

And don't be afraid to change it!

Colour theory is a guide, not a rulebook.

One Final Tip — Save Your Colour Palettes!

When you create a colour combination that works, save it.

Keeping a collection of your favourite palettes can save so much time when you're creating new products.

You could organise them by:

🍂 Autumn
🎄 Christmas
🌸 Spring
☀️ Summer
👶 Baby
🎂 Birthday
💍 Wedding
🌈 Bright & Playful
🤎 Neutral & Boho
💕 Pastels

Over time, you'll build your own little colour library that you can return to whenever you need inspiration.

Final Thoughts

Understanding the colour wheel doesn't mean you have to follow strict design rules.

It's simply another tool in your creative toolkit.

Use it when you're stuck, experiment with different combinations and pay attention to how colours make your designs feel.

The more you play with colour, the more instinctive choosing palettes becomes.

And sometimes?

The colour combination that technically shouldn't work is the one you absolutely love.

If it works for your design, that's what matters. 🎨✨
