Colour is often the first thing people notice about a brand, and the last thing they remember when they leave a page. That makes it tempting to choose colours because they look fashionable, or because a favourite shade feels right in the moment. A better approach is to choose with purpose: each colour should have a job, a place where it is used, and a reason for being there. When colours are chosen this way, a brand looks intentional rather than accidental.
Give Every Colour a Job
Start with a small palette, not a large one. Most brands need one main colour, one or two supporting colours, and a set of neutrals for backgrounds and text. The main colour carries recognition, so it should appear in the logo, in headings, and in key buttons. Supporting colours add warmth, contrast, or emphasis, but they should not fight the main colour for attention. Neutrals do the quiet work: they give text room to breathe and keep long pages comfortable to read.
Think about use before you think about beauty. A colour that looks striking on a large poster may be hard to read as small text, and a pale shade that looks elegant on a light background may disappear on a photograph. Test each colour as a button, as a heading, as a link, and as a background.
Test Readability and Contrast
Readability is not optional, and it cannot be judged by eye alone on a single screen. Check text against its background in bright light and in dim light, at small sizes and on a phone, not only on a large monitor. Pay special attention to links, buttons, and form labels, because these are the places where low contrast causes real problems. If people have to strain to read a price, a date, or a call to action, the colour choice is failing, however attractive it looks.
Consistency matters just as much as contrast. Record the exact values for each colour, including the shades you use for hover states, borders, and disabled buttons.
Keep the Palette Small and Flexible
A small palette is easier to use well. It forces you to make clear choices, it keeps pages from looking crowded, and it makes new material faster to produce, because you are not inventing a new shade for every section. Colour should sit comfortably beside your other choices, as explained in building a brand identity from scratch, and it should not overpower the words on the page, which is why typography choices that shape brand voice deserve equal care.
Finally, revisit the palette after it has been used in real work. Notice which colours you reach for most often, which ones you avoid, and where readers hesitate. A palette that survives contact with real pages, real photographs, and real text is a good one.
