Colour is everywhere, but choosing and identifying colours is more than simply knowing that something is “blue” or “red.” Colour theory helps us understand how colours are created, how they relate to one another, and how they can be combined to create attractive and meaningful designs.

Whether you are designing a logo, choosing colours for a website, creating social media graphics or simply trying to understand why certain colours look good together, learning the basics of colour theory can be extremely useful.

What Is Colour Theory?

Colour theory is the study of how colours interact, relate and work together.

One of the most useful tools for understanding colour theory is the colour wheel.

The colour wheel organises colours in a way that makes it easier to see relationships between them.

The Three Primary Colours

At the foundation of the traditional colour wheel are three primary colours:

🔴 Red
🟡 Yellow
🔵 Blue

They are called primary colours because, in traditional colour theory, they are used to create other colours.

Secondary Colours

When two primary colours are mixed, they create secondary colours:

Red + Yellow = Orange 🟠

Yellow + Blue = Green 🟢

Blue + Red = Purple/Violet 🟣

So the six basic colours are:

Red → Orange → Yellow → Green → Blue → Purple

These form the foundation of the traditional colour wheel.

How to Identify Different Colours

Identifying colours becomes easier when you understand three important characteristics:

1. Hue

Hue simply means the basic colour itself.

For example:

• Red is a hue.
• Blue is a hue.
• Green is a hue.
• Yellow is a hue.

When someone asks, “What colour is this?”, they are usually asking about its hue.

2. Saturation

Saturation describes how strong or intense a colour is.

A highly saturated red looks bright and powerful.

A less saturated red looks softer and closer to grey.

For example:

🔴 Bright red → high saturation

🩶 Muted/dull red → lower saturation

This is why two objects can both technically be “red” but look very different.

3. Value or Brightness

Value refers to how light or dark a colour is.

For example:

🔵 Light blue

🔵 Medium blue

🔵 Dark blue

They are all blue, but their values are different.

Understanding hue, saturation and value is one of the easiest ways to become better at identifying colours.

Tints, Shades and Tones

You will also hear three important terms in colour theory.

Tint

A tint is created by adding white to a colour.

For example:

Red + White = Pink

So pink can be thought of as a tint of red.

Shade

A shade is created by adding black to a colour.

For example:

Blue + Black = Dark Blue

Tone

A tone is created by adding grey to a colour.

This generally makes the colour appear softer or less intense.

Understanding these three concepts helps explain why there can be hundreds of variations of what we casually call the same colour.

Warm and Cool Colours

Colours are also commonly divided into warm and cool colours.

Warm Colours

These generally include:

🔴 Red
🟠 Orange
🟡 Yellow

They are often associated with energy, warmth, excitement and attention.

Cool Colours

These generally include:

🔵 Blue
🟢 Green
🟣 Purple

They are often associated with calmness, nature, stability and tranquillity.

However, the perception of a colour can change depending on the colours surrounding it.

Understanding Colour Relationships

The colour wheel also helps us identify combinations that work well together.

Complementary Colours

These are colours positioned opposite each other on the colour wheel.

Examples include:

Blue + Orange

Red + Green

Yellow + Purple

Because they have strong contrast, complementary colours can make designs stand out.

Analogous Colours

These are colours that sit next to each other on the colour wheel.

For example:

Blue + Blue-Green + Green

They generally create a harmonious and comfortable appearance.

Triadic Colours

These involve three colours that are evenly spaced around the colour wheel.

A traditional example is:

Red + Yellow + Blue

Triadic combinations can create vibrant and energetic designs.

How Can You Tell What Colour Something Really Is?

Sometimes identifying a colour by looking at it isn’t enough.

For example, you might look at a particular shade and call it blue, while someone else might call it teal.

This is where digital colour identification becomes useful.

RGB

RGB stands for:

Red – Green – Blue

Digital screens create colours by combining different amounts of red, green and blue light.

A colour can therefore be represented by an RGB value.

HEX Codes

For websites and digital design, colours are commonly represented using HEX codes.

For example:

#FF0000 = Red

#0000FF = Blue

#00FF00 = Green

A HEX code allows designers to reproduce the same colour consistently across digital materials.

Colour Pickers

If you see a colour you like in an image, website or design, you can use a colour picker/eyedropper tool in software such as Canva, Photoshop or other design applications.

You simply select the colour, and the software can give you its:

• HEX code
• RGB values
• Sometimes HSL/HSB values

This is particularly useful when creating a brand identity.

Why Colour Theory Matters for Branding

Colour isn’t just decoration.

Businesses use colour to create a particular identity and feeling.

For example, a company might choose:

Blue to communicate trust and professionalism.

Green to communicate growth, nature or sustainability.

Orange to communicate energy and creativity.

Black to communicate sophistication or authority.

However, these associations aren’t universal. Culture, context and the particular shade of a colour can change how people perceive it.

This is particularly important when creating brands that operate across different African countries and international markets.

Colour Theory and Just4WomenAfrica

For a platform like Just4WomenAfrica, colour choices should be intentional.

Rather than simply asking:

“Which colours look beautiful?”

we should ask:

“What do we want people to feel when they see Just4WomenAfrica?”

Do we want the brand to communicate:

Empowerment?

African identity?

Professionalism?

Community?

Growth?

Confidence?

Once those qualities are identified, colour theory can help create a palette that supports the brand’s identity.

The Bottom Line

Learning colour theory doesn’t mean memorising hundreds of colours.

Start with the basics:

Hue = What colour is it?

Saturation = How intense is it?

Value = How light or dark is it?

Then learn the colour wheel, warm and cool colours, tints, shades, tones and colour relationships.

Once you understand these concepts, you’ll begin to look at colours differently — not just seeing “blue”, but recognising what kind of blue it is, how strong it is, how light or dark it is, and which colours will work well with it.
