Color Converter — Translate Any Color Between HEX, RGB, HSL, HSV, and CMYK
Color values exist in multiple formats because different tools, workflows, and output media use fundamentally different color models. Web browsers and CSS use hexadecimal notation (#FF5733) and RGB functional notation (rgb(255, 87, 51)) because monitors mix red, green, and blue light to produce color. Design tools like Figma and Adobe XD work primarily in RGB but show HSL (hue, saturation, lightness) because HSL maps to how designers think about color — adjusting lightness without changing hue, or increasing saturation without changing the base color. Print production uses CMYK (cyan, magenta, yellow, key/black) because inkjet and offset printing subtracts color from white paper rather than adding light. The same orange that is #FF5733 in CSS is rgb(255,87,51) in a canvas API, hsl(11, 100%, 60%) in a CSS variable, and approximately cmyk(0, 66, 80, 0) for print production. Switching between these systems without a converter means doing the math by hand.
HSL is the color format that most closely matches human color perception and design reasoning. The hue component (0–360 degrees on the color wheel) defines the base color: 0 is red, 120 is green, 240 is blue, with every other color distributed between. The saturation component (0–100%) defines how vivid the color is: 0% is gray regardless of hue, 100% is the most vivid expression of that hue. The lightness component (0–100%) defines the tone: 0% is black, 100% is white, 50% is the pure hue. This three-axis model means that creating a lighter version of a brand color requires only increasing the lightness value while keeping hue and saturation constant — a trivial operation in HSL that requires complex calculation in HEX or RGB.
Color accuracy across formats is not perfectly lossless because different color models have different gamuts. RGB assumes the sRGB color space, which is the standard for web and consumer displays. CMYK values depend on the specific ink set and paper stock used in the printing process — the same CMYK percentages produce different visible colors on coated versus uncoated paper. Converting from a vivid RGB color to CMYK for print often requires gamut mapping because some RGB colors — particularly vivid greens, electric blues, and bright oranges — simply cannot be reproduced in CMYK ink and must be shifted to the nearest printable equivalent. The converter performs the mathematical conversion and flags values that fall outside printable CMYK gamut so the discrepancy is visible before a print job reveals the mismatch.
