Why Color Matters on the Web
Color is the first thing users notice when they land on your website. Research shows that people form an opinion about a product within 90 seconds, and up to 90% of that assessment is based on color alone. Your color palette communicates your brand personality, guides user attention, and influences purchasing decisions.
Building Your Color Palette
Start with one primary color that represents your brand. Then choose a secondary color that complements it. Add a neutral (white, gray, or off-white) for backgrounds and a dark color for text. Finally, pick an accent color for CTAs and important elements. Most effective websites use no more than 4-5 colors consistently.
Color psychology in web design:
- Blue conveys trust and professionalism (finance, tech)
- Green suggests growth and health (wellness, sustainability)
- Purple communicates creativity and luxury (beauty, premium brands)
- Orange and red create urgency (CTAs, sale badges)
- Black and gray convey sophistication and elegance (luxury, minimal design)
Testing for Accessibility
Always ensure your color combinations meet WCAG accessibility standards. Your text should have a contrast ratio of at least 4.5:1 against its background. This is not just about compliance — accessible design improves readability for everyone, including users in bright sunlight or on low-quality screens.
