Color Converter

The Color Converter translates a single color between every format used in modern web and design work: HEX (#3366ff), RGB / RGBA (51, 102, 255), HSL / HSLA (hue, saturation, lightness), and HSB/HSV values used by design tools like Photoshop and Figma. Enter a color in any one format and instantly see it expressed in all the others, alongside a live preview swatch so you can confirm it's the exact shade you intended before dropping the code into a stylesheet. Front-end developers use this tool daily when translating a designer's Figma or Sketch palette into CSS custom properties, when building a Tailwind config with a custom color scale, or when debugging why a color looks different across two different rendering contexts (a common source of confusion is that CSS accepts both #rrggbb hex and rgb() notation, but a design spec might hand you HSL values that need converting before they're usable in a design token file). Designers and brand teams use it to check a brand color's exact HSL lightness value when generating tints and shades for hover states, disabled states, and dark-mode variants, since adjusting the L channel of HSL keeps hue and saturation constant, giving a much more natural gradient of shades than naively lightening RGB channels. Understanding the formats helps you pick the right one for the job. HEX is compact and ubiquitous but opaque to human intuition — you can't look at #3366ff and know it's a medium-bright blue without mentally converting it. RGB is the raw additive-light model your monitor actually renders, useful for canvas and WebGL work. HSL is by far the most intuitive for design work because hue is a single 0–360 value on the color wheel, saturation controls vividness, and lightness controls how close to black or white the color sits — which is exactly the mental model most designers use when picking a palette. HSB/HSV is nearly identical to HSL but swaps lightness for "brightness/value," which is the model most photo-editing and design software exposes in its color picker, so converting between HSL and HSB is often necessary when moving a value from a design tool into CSS. A practical workflow tip: when building a color system, pick your base hue and saturation in HSL, then generate a scale of 5–9 shades by stepping the lightness value in even increments (e.g., 95%, 85%, 70%, 50%, 35%, 20%, 10%) — this produces a far more visually consistent ramp than trying to eyeball hex codes. Also double check alpha values when copying RGBA or HSLA into CSS, since a missed alpha channel is a very common source of "why is my overlay solid instead of translucent" bugs. All conversion happens instantly and entirely client-side in your browser; no color values, palettes, or brand assets you enter are ever transmitted to a server. Pair this tool with a contrast checker when picking text colors for accessibility, and with the CSS Minifier when you're ready to ship your finished stylesheet.
