Using colour is a great way to make your website look good, but it also plays a large role in how visitors feel and whether they stick around. Your chosen colour scheme can make or break your site’s visual appeal. However, there are millions of possible combinations, and it can be overwhelming to stick with only one.
Fortunately, there is a straightforward way to pick the best website colour scheme. If you follow the right steps, you can create a seamlessly beautiful design.
Understand the Basics of Colour Theory
Before mixing and matching colours, take a step back to understand what makes certain combinations work. Colour theory is a tool that many designers use to create a more engaging and user-friendly website.
Research shows that the right colour scheme can do more than catch someone’s eye. Shades that align with psychological cues and cultural preferences can help users feel more connected to your brand. This emotional connection boosts how usable your website feels, increases trust and encourages visitors to stick around longer.
Colour also influences mood. Warm tones – red, orange or gold — often feel romantic and cozy, while cool hues like blues and greens feel calming or sophisticated. Choosing the right mood can shape how people interact with your website, whether you want them to feel excited, reassured, inspired or relaxed.
At the heart of colour theory is the colour wheel, which helps you understand how different shades work together. Here are a few key relationships to know:
- Complementary: Colours are opposite on the wheel — like blue and orange. They create high contrast and energy.
- Analogous: Colours, such as green and blue, sit side by side. These feel more cohesive and calming.
- Triadic: These shades are evenly spaced around the wheel — such as red, yellow and blue — creating balance and vibrancy.
- Monochromatic: This scheme sticks to different shades and tints of a single colour, which can look sleek and modern.
Memorizing every rule is not a requirement, but understanding these basics will give you an idea of how to build a great colour palette that supports your site’s goals.
Define Your Brand’s Personality and Goals
Once you have a handle on how colour works, you can determine what your website needs to communicate. This is because colour choices can offer a certain kind of experience you want to create for your visitors, so it is important to ask yourself these questions:
- What feelings or traits should people associate with your brand?
- Are you aiming for playful and energetic or calm and professional?
- Who is your target audience, and what appeals to them?
It is also helpful to look at your competitors and see how they incorporate colour. This step can show you how to stand out and be different from the rest.
Your colour scheme should work with your brand identity. Once you have clarified your voice and vibe, choosing a palette that reinforces it becomes easier.
Pick a Dominant Colour First
Now it is time to choose your primary colour — the one that will appear most often across your website and become most closely associated with your brand.
Your dominant colour should reflect the overall feeling or message you want to send. If your brand is about raising vibration and keeping people excited, reds and oranges can be a great fit. However, a project that embodies trust and professionalism works best with blue. For luxury or elegance, consider deep purples, blacks or metallics.
This colour will show up in major areas of your site, like:
- Your logo and header.
- Backgrounds or hero sections.
- Buttons and key calls-to-action (CTAs).
- Icons or highlights.
A good rule of thumb is that your main colour should be memorable but not overpowering. It should set the tone for the rest of your content. For example, Spotify’s signature green stands out in the tech space and communicates energy and creativity, which is fitting for a music platform. HubSpot uses a warm orange that feels friendly and inviting, reinforcing its approachable brand image.
Build a Colour Scheme Around Your Dominant Colour
Once you have locked in your dominant colour, you will need to build a complete scheme that complements it and supports your website’s overall design. A strong palette can influence people’s feelings about your brand at first glance.
Research from Adobe found that 16% of consumers say it is the first thing they notice when looking at a brand, and one in two people have chosen one over the other due to colour alone. Therefore, your choices affect how users engage with your site and whether they will remember you.
To build out your palette, you will typically want:
- A primary colour.
- One or two secondary colours to complement your primary.
- An accent colour to highlight important features.
- A neutral base to keep things balanced.
Make it easier on yourself and choose shades using online tools that let you generate schemes based on your primary colour choice and explore pairings.
Think About Accessibility and Contrast
A beautiful colour scheme is only effective if visitors can read and interact with it. That is where you should consider accessibility and the right contrast. When there is little to no contrast between your text and background, users may struggle to read your content, especially those with visual impairments or colour blindness.
The Web Content Accessibility Guidelines (WCAG) recommend that body text should have a 4.5:1 minimum contrast ratio against the background. For larger text, a 3:1 ratio is acceptable. This ensures the words remain legible for most users, regardless of screen settings or eyesight.
In practical terms, this means avoiding light gray text on a white background or dark red text on black. High-contrast pairings are safer, more accessible choices. You can use WebAIM’s contrast checker to make sure your colour combinations meet the required standards. It is as simple as entering your text and background hex codes to get a pass or fail rating.
Limit the Number of Colours Used
It is tempting to use every shade you love, but less is usually more in colour schemes. Too many can make your website feel busy, disorganized or overwhelming.
A helpful rule to follow is the 60-30-10 principle, which gives designers direction on how much colour to use for websites:
- 60% of your site should use your dominant colour — think backgrounds or large content areas.
- 30% can feature a secondary colour — often used for navigation, cards or sections.
- 10% is for your accent colour, which draws attention to buttons, CTAs or important highlights.
This ratio keeps your design visually balanced and gives the user a clear hierarchy of where to look first and what to do next. You will also want to build in neutrals to give your main colours space to breathe. These subtle tones prevent your site from looking too loud and make your content easier to read.
Test and Iterate Before Finalizing
Once you have your colour scheme set, seeing how it performs before you hit publish is important. Sometimes, a palette can feel off when applied across the site or viewed on different screens.
Start by previewing your website on different devices. A colour that looks great on a high-end monitor may appear dull or hard to read on a phone. You will also want to view your site in light and dark environments to check for readability.
If you make major changes or launch a new design, consider running A/B tests. You can compare two versions of a page to see which performs better in terms of clicks, conversions and time spent there.
It also helps to gather feedback from users and design communities. Fresh eyes may spot contrast issues or emotional disconnects that you overlooked.
Let Colour Work for You
Choosing the right colour scheme for your website may feel intimidating at first. You may even feel pressured to pick all your shades at once. However, there is always a strategy for creating a palette, so use the right steps to build a scheme that will help you create a loyal following.
