Colour Theory Basics and Key Principles

Colour theory is the study of how colours interact, contrast, and complement one another. It’s a set of principles and guidelines that help designers create visually pleasing colour combinations. Here are some key principles to help you get started:

The Colour Wheel

The colour wheel is a visual representation of the relationship between colours. It consists of 12 colours: three primary colours (red, blue, and yellow), three secondary colours (green, orange, and violet), and six tertiary colours (mixtures of primary and secondary colours). The colour wheel helps you understand how colours relate to one another and serves as a guide for creating harmonious colour schemes.

Hue, Saturation, and Value

Hue – refers to the pure colour itself, such as red, blue, or yellow.

Saturation – Describes the intensity or purity of a colour. A fully saturated colour is vivid and bright, while a desaturated colour appears more muted and grey.

Value – Refers to the lightness or darkness of a colour. A high-value colour is light, while a low-value colour is dark.

Understanding these properties will help you create more balanced and cohesive colour schemes.

The Importance of Colour in Web Design

Colour is a powerful design element that can greatly impact the overall look and feel of your website. Here’s why it’s essential to pay attention to colour in web design:


The right colour palette can enhance the visual appeal of your site, making it more attractive and inviting to users.

Brand Identity

Colour plays a crucial role in establishing and reinforcing your brand identity. Consistent use of brand colours across your website and other marketing materials can help build brand recognition and trust.

Emotions and Psychology

Different colours can evoke various emotions and influence users’ perceptions and actions. For example, blue is often associated with trust and stability, while red can signify excitement or urgency. Choosing the right colours can help you create the desired emotional response and user experience.

Usability and Accessibility

Using contrasting colours for text and background can improve readability and ensure your content is accessible to all users, including those with visual impairments.

Creating Colour Schemes

There are several types of colour schemes you can use in web design, each with its unique characteristics. Here are some popular colour schemes and how to create them:


A monochromatic colour scheme consists of different shades, tints, and tones of a single hue. To create a monochromatic scheme, choose a base hue and adjust its saturation and value to generate a range of variations. This type of colour scheme is simple, visually cohesive, and easy on the eyes.


An analogous colour scheme includes colours that are adjacent to one another on the colour wheel. For example, you could choose blue, green, and yellow. Analogous schemes create a harmonious and balanced look, as the colours share similar characteristics.


Complementary colours are opposite one another on the colour wheel, such as red and green, or blue and orange. A complementary colour scheme offers a high contrast and can create a dynamic, visually engaging design. Be cautious with complementary colours, as they can be overpowering if not balanced correctly.


A triadic colour scheme consists of three colours evenly spaced around the colour wheel, such as red, yellow, and blue. This type of scheme offers a vibrant and energetic look, but it’s essential to balance the colours to avoid visual chaos.

Tips for Choosing the Perfect Colour Palette

Now that you know the basics of colour theory and different colour schemes, here are some tips to help you choose the perfect palette for your web design projects:

Start with Your Brand Colours

If you’re designing a website for a specific brand, use the brand’s colours as a starting point. This will help establish a consistent brand identity and make your design more recognizable.

Consider the Mood and Tone

Think about the emotional response you want your website to evoke and choose colours that align with that mood. For example, if you’re designing a website for a spa, you might choose calming colours like blue and green.

Use Contrast for Readability

Ensure there’s enough contrast between your text and background colours to make your content easily readable. High contrast combinations, like dark text on a light background, are generally more accessible.

Limit Your Palette

Too many colours can make your design appear cluttered and chaotic. Stick to a limited palette of 3-5 colours to maintain visual cohesion and simplify decision-making.

Test on Multiple Devices

Colour rendering can vary across different devices and screens. Test your chosen colours on multiple devices to ensure they appear consistent and visually appealing.
