Color Converter - HEX, RGB, HSL | Hexa

Why Designers and Developers Need Color Conversion

Colors are represented differently across tools and platforms. CSS uses HEX (#ff5733) or RGB (rgb(255, 87, 51)). Design software might use HSL for easier adjustment of hue, saturation, and lightness. APIs and design systems often expect one format while your source provides another. Converting manually is error-prone—a typo in a HEX code can produce a completely wrong color. Our converter handles HEX, RGB, and HSL instantly, so you can paste a color from any source and get the equivalent in the format you need. See Web colors on Wikipedia for the full picture of web color systems.

Understanding HEX, RGB, and HSL

HEX uses a 6-character code (plus optional alpha) to represent red, green, and blue. Each pair of characters is a hex value 00–FF. #ff0000 is pure red; #00ff00 is pure green. Widely used in CSS, design tools, and web development.

RGB expresses the same red, green, blue values as numbers 0–255. rgb(255, 0, 0) is pure red. More readable for some developers; CSS and many APIs support it.

HSL (Hue, Saturation, Lightness) describes color differently. Hue is the color angle (0–360°). Saturation and lightness control intensity and brightness. Useful when you want to create color variations—change lightness to get lighter or darker shades of the same hue.

Common Conversion Scenarios

Design to code: Your designer sends a HEX from Figma. You need RGB for a chart library. Convert in one step.

API integration: An API returns colors in RGB. Your frontend expects HEX. Convert before rendering.

Color manipulation: HSL makes it easy to create palettes—same hue, different saturation and lightness. Convert from HEX to HSL, adjust, convert back.

Accessibility: When checking contrast ratios. WCAG guidelines often require luminance values derived from RGB. Converting HEX to RGB is the first step for computing relative luminance and ensuring text meets accessibility standards.
