Color Converter
Convert between HEX, RGB and HSL color formats with live preview and color picker.
Why Designers and Developers Need All Three Color Formats
CSS, design tools and image editors each have preferred color formats — CSS uses hex codes (#2563eb) and RGB (rgb(37,99,235)), while design tools (Figma, Adobe XD) display HSL for intuitive color manipulation. Converting between formats is a constant need: copying a hex color from a design file to CSS, converting a brand color from RGB to HSL for creating lighter/darker variants, or checking WCAG contrast ratios. Our converter handles all three formats with live preview.
Frequently Asked Questions
How to convert HEX to RGB in CSS? ▼
In CSS you can use hex directly (#2563eb) or convert to rgb(37,99,235). Modern CSS also supports hsl(221,83%,53%). Our converter instantly shows all three for any input color. CSS4 also supports oklch() for more perceptually uniform color manipulation.
What is HSL and why is it better for design? ▼
HSL (Hue, Saturation, Lightness) is more intuitive for humans than hex or RGB. Hue: the color (0–360° on a color wheel), Saturation: how vivid vs grey (0–100%), Lightness: how light vs dark (0–100%). To create a lighter version of a color: increase Lightness. To create a muted version: decrease Saturation. This makes brand palette creation intuitive.
How to check if two colors have enough contrast for accessibility (WCAG)? ▼
WCAG 2.1 requires contrast ratio of 4.5:1 for normal text, 3:1 for large text (18pt+ or 14pt bold) against the background. Our converter shows whether text is better displayed in black or white on the selected color based on luminance calculation. For full WCAG compliance checking, use the WebAIM Contrast Checker.
What is the difference between RGB and RGBA? ▼
RGB defines a color using Red, Green, Blue values (0–255 each). RGBA adds an Alpha channel (0.0–1.0) for transparency: rgba(37,99,235,0.5) = 50% transparent blue. HSLA similarly adds alpha to HSL. Our converter shows RGB — add the alpha value manually for RGBA: rgba([R],[G],[B],[alpha]).
How to find the HEX color code of any color on screen? ▼
Windows: use the built-in Color Picker in PowerToys or Paint. Mac: use the Digital Color Meter app (Applications → Utilities). Browser: use browser DevTools → Styles panel, click any color swatch to open the color picker. Our Color Picker from Image tool also extracts colors from uploaded images.
