When you visit a professional website, the colours feel coherent — the buttons match the headings, the backgrounds feel consistent, and nothing clashes in a way that feels distracting or amateurish. That consistency comes from a defined colour scheme: a deliberate set of colours chosen to work together and applied consistently throughout the site.
When a website has no colour scheme — using whatever colours felt right in the moment, picking a different button colour on each page, or mixing dozens of shades — it gives the impression that the business itself is disorganised. Visitors do not consciously think this, but they feel it.
How Many Colours Do You Actually Need?
Most professional small business websites use three to five colours. More than that and the site starts to feel cluttered and inconsistent. Fewer than three and you may struggle to create enough visual variety to guide visitors' attention.
A practical approach for most small businesses is to define:
- A background colour. Usually white, off-white, or a very light shade of your brand colour. Dark backgrounds can look great but make body text harder to read for long periods.
- A primary text colour. Usually near-black rather than pure black — a very dark grey (such as #222222) is often easier on the eye than pure black (#000000) against white.
- An accent colour. Your brand colour — used for buttons, links, headings, and anything you want to draw attention to. This is the colour most associated with your business.
- A secondary accent (optional). A complementary colour for hover states, borders, or secondary buttons. Often a lighter or darker shade of the primary accent.
Keeping it to these four roles and filling each with a single colour gives you all the variety you need while keeping the site looking cohesive.
The Rule That Matters Most: Contrast
The single most important principle in choosing website colours is contrast — specifically, the contrast between your text and its background. Text that is hard to read because the colours are too similar is one of the most common problems on small business websites.
A very common mistake is using a mid-tone grey text on a white background — it looks elegant in a screenshot but is genuinely tiring to read on a screen, particularly on a phone in bright sunlight. Dark text on a light background, or light text on a dark background, is almost always easier to read.
There is a free tool called the WebAIM Contrast Checker where you can paste any two colours and instantly see whether they meet readability standards. It takes under a minute to use and is worth checking for every text and background combination on your site. Google also uses contrast ratios as part of its accessibility assessment of websites.
Should Your Website Colours Match Your Logo?
Yes, where possible. If you already have a logo with defined brand colours, your website should use those same colours so that your business looks consistent everywhere a customer encounters it — business cards, social media, website, van signage.
If you do not know the exact colour codes used in your logo, your designer or printer should be able to provide them. Colours are typically specified in three formats: HEX codes (like #FF5A1F), RGB values (used for screens), and CMYK values (used for print). For a website, you want the HEX or RGB version.
If your logo uses a very bright or saturated colour, you may not want to use it as the background of your entire website — it could be overwhelming. In that case, use it as the accent colour for buttons and highlights, and pair it with a neutral background and text colour.
How to Choose Colours If You Are Starting From Scratch
If you do not have existing brand colours, start by thinking about what impression you want your business to give. Colours carry associations that affect how visitors feel:
- Blue is associated with trust, reliability, and professionalism — common in finance, healthcare, and trades.
- Green suggests nature, health, growth, and calm — used widely by environmental businesses, wellness brands, and landscapers.
- Orange and yellow feel energetic, friendly, and approachable — common in food, childcare, and creative industries.
- Black and dark grey suggest premium quality, sophistication, and authority — used by luxury brands and high-end service providers.
- Red creates urgency and draws attention — effective for calls to action but overpowering as a dominant colour.
These are tendencies, not rules. What matters more is that your chosen colours feel right for your specific business and customers, and that they are applied consistently.
Tools That Make Colour Choosing Easier
You do not need to pick colours by instinct. Several free tools do most of the work for you:
- Coolors — generates colour palettes with one press of the spacebar. You can lock colours you like and keep generating until the combination feels right.
- Adobe Colour — lets you build palettes based on colour theory rules and extract colours from a photo (useful if you want to match a colour in your logo or a photograph).
- Realtime Colors — shows you exactly how a colour combination will look on a real webpage layout, so you can judge it in context rather than as abstract swatches.
Even spending thirty minutes with one of these tools is enough to arrive at a colour scheme that looks considered and professional — without any design experience.
