Other tools you may find usefulUI color scheme tester - apply a palette to a website mockup
Choosing a beautiful color palette is one thing - seeing what it looks like on a real page is another. The tool applies your palette (primary, secondary, background, text, accent) to a responsive page mockup with header, tabs, form and footer.
Mockup elements for testing
Navigation: logo + menu + CTA button (primary color). Hero section: background (primary/gradient) + header (text on background). Product/service cards: card background + title + description + badge. Form: input border + focus ring + label + submit button. Footer: dark background + links + social icons.
Colors in the design system
Primary: the main color of the brand (CTA, links, accents). Secondary: supplementary (tags, badges, highlights). Background: page background (white, near-white, dark mode). Surface: background of tabs/UI elements. Text: main text (heading, body). Muted: less important text (timestamp, caption). Error/Success/Warning: status colors.
WCAG Contrast and Accessibility
WCAG 2.1 AA: normal text ≥ 4.5:1, large text ≥ 3:1, UI components ≥ 3:1. WCAG AAA: normal text ≥ 7:1. The tool automatically checks the contrast of each color/background pair and warns about violations. Red = fail AA. Yellow = pass AA, fail AAA. Green = AAA pass.
Dark mode testing
Toggle dark/light mode: tool shows both versions of the mockup. Dark mode: background reversed, surface darker, text lighter. CSS palette variables: --color-background: white; @media (prefers-color-scheme: dark) { --color-background: #1a1a1a; }. OKLCH makes it easy to generate dark mode variants.
Frequently asked questions
How to choose a good primary color for your brand?
Industry analysis: blue (tech, finance, trust), green (ecology, health), red (energy, urgency, gastronomy), purple (luxury, creativity). Study: Elliot (2010) showed the influence of colors on behavior. But: brand recognition is more important than the "right" industry color.
How many colors should the page palette have?
60-30-10 rule: 60% dominant (background), 30% secondary (elements), 10% accent (CTA). Minimal palette: primary, secondary/accent, background, text. Full design system: primary (5 shades), neutral (9 shades), semantic (error, success, warning, info). Too many colors = chaotic UI.
How to test palettes for dark mode?
Do not invert colors 1:1. Background: very dark (not pure black #000 – better #121212 or #1E1E1E). Surface: slightly brighter than bg. Text: not pure white (better #E5E5E5). Primary: A brighter variant is often needed. Saturation: slightly reduced in dark mode.
How do I export a palette to Figma/Tailwind?
Figma: copy HEX to Color Styles or Variables. Tailwind: in tailwind.config.js extend.colors: { brand: "#FF5733" }. CSS variables: :root { --color-primary: #FF5733; }. Style Dictionary (Amazon): JSON → tokens for multiple platforms at once (CSS, iOS, Android).
