Color Converter
Convert a color between HEX, RGB and HSL.
#4f46e5rgb(79, 70, 229)hsl(243, 75%, 59%)About the Color Converter
Convert any color between HEX, RGB, and HSL simultaneously — drag the channel sliders, drop a hex code, or pick visually and watch all three formats update in sync with a live preview swatch. Each value copies as ready-to-paste CSS. Conversion runs entirely in your browser with instant, exact math; no account, no limits, and no color you enter ever leaves your machine.
Three formats, three mental models
HEX packs the red, green, and blue channels into six hex digits — compact, ubiquitous, and the lingua franca of design files. RGB spells the same thing out numerically, which reads clearly inside rgba() contexts and JavaScript. HSL reframes the color as human concepts: hue as an angle around the wheel, saturation as intensity from gray to vivid, lightness from black to white. All three describe identical colors; the best choice depends on whether you are copying from a designer, writing CSS, or thinking about relationships between shades. A useful habit is storing one canonical format in your design tokens and converting at the edges, rather than letting three spellings of the same color drift apart across a codebase.
When HSL earns its place
Try answering this in RGB: what color is halfway between this blue and that teal? Nearly impossible. In HSL it is obvious — average the hue angles. The same intuition powers everyday styling tasks: darken a hover state by dropping lightness ten points, build a palette of muted accents by holding hue constant while lowering saturation, or generate a tint ladder by stepping lightness. RGB answers what a color IS; HSL answers how to MOVE it, which makes the converter handy for exploring variations around a brand color before committing any to code.
Alpha and transparency
This converter works with fully opaque six-digit hex colors. CSS handles transparency separately when you need it: append an alpha channel in functional notation — rgba() and hsla() take opacity as a fourth value, and eight-digit hex places it as the final pair. Convert your base color here first, then add transparency at the point of use in your stylesheet; keeping the opaque definition as the source of truth tends to keep theme files saner.
A note on accessible contrast
Converting formats tells you what a color is, not whether it works. Before shipping text styles, check luminance contrast between foreground and background against WCAG guidance — roughly 4.5 to 1 for body text, 3 to 1 for large text — because a color that survives conversion beautifully can still flunk readability at low opacity or on tinted surfaces. Lightness sliders make quick contrast experiments easy: nudging lightness a few points often rescues a failing pairing without changing the hue anyone associates with your brand.
