Color tools for designers and developers
From converting HEX codes to RGB, HSL, and CMYK, to generating accessible color palettes and checking contrast ratios against WCAG 2.1 AA/AAA standards — this hub covers the color-related tasks that come up most frequently in UI design and web development.
For designers and developers: The Color Contrast Checker is particularly valuable for accessibility compliance work — it tells you instantly whether your color combinations meet WCAG AA (4.5:1) or AAA (7:1) contrast requirements for normal and large text.
5 Color Utility Tools
Each tool is purpose-built for a specific task. No bloat, no gated features.
Color Converter
Convert any color between HEX, RGB, HSL, HSV, and CMYK formats with instant live output. Enter a color in any format and get all equivalent representations simultaneously — essential for working across different design and development tools.
Hex to RGB Converter
Convert HEX color codes to their RGB equivalents. Essential when CSS requires rgb() or rgba() values, or when passing colors to JavaScript-based color manipulation libraries.
RGB to Hex Converter
Convert RGB values to HEX color codes. Useful when a design spec provides RGB values that need to be implemented as HEX in CSS, HTML attributes, or design system tokens.
Color Palette Generator
Generate cohesive color palettes from a single base color — producing complementary, analogous, triadic, and split-complementary schemes with HEX codes ready to copy. Useful for brand work, UI design, and design system creation.
Color Contrast Checker
Check the contrast ratio between any foreground and background color pair against WCAG 2.1 AA (4.5:1) and AAA (7:1) standards. Instantly see whether your color combination passes for normal text, large text, and UI components — with a visual pass/fail indicator.
Common scenarios these tools solve
Purpose-built for professionals and everyday users who need fast, reliable results.
UI Designers
Convert between color formats as you move between design tools, and check contrast ratios before handing off to developers.
Front-End Developers
Convert HEX codes from design specs to RGB/HSL values needed in CSS, and validate palette accessibility during implementation.
Accessibility Auditors
Use the Color Contrast Checker to identify failing text/background combinations and replace them with WCAG-compliant alternatives.
Print Designers
Convert RGB or HEX colors to CMYK values needed for print production and physical material specifications.
Brand Designers
Generate cohesive color palettes from a brand primary color for use across marketing materials, websites, and product design.
App Developers
Ensure UI color combinations meet platform accessibility guidelines and maintain visual consistency across light/dark themes.
