Color Converter

A color converter translates a color from one notation into equivalent values in other color models. Designers and developers routinely work with multiple formats: HEX in design tools and CSS, RGB on screens, HSL for intuitive hue adjustments, CMYK for print workflows, and OKLCH for perceptually uniform palettes in modern CSS. Manually converting between them is tedious and error-prone — especially when alpha channels, three-digit HEX shorthand, or modern space-separated CSS syntax are involved.

Our free online color converter accepts input in any common format. Paste #FF5733, rgb(255, 87, 51), hsl(11, 100%, 60%), or even CSS named colors like coral. The tool validates your input, shows a large live swatch, and displays every major format simultaneously with one-click copy buttons.

HEX (hexadecimal) is the most common web format — six characters representing red, green, and blue channels in base 16. Three-digit shorthand like #f53 expands to #ff5533. Eight-digit HEX adds an alpha channel for transparency. RGB expresses the same channels as decimal values from 0 to 255. CSS Color Level 4 also allows space-separated syntax like rgb(255 87 51 / 0.5).

HSL (hue, saturation, lightness) describes colors in a way that matches human intuition: hue is the angle on the color wheel (0–360°), saturation is colorfulness (0–100%), and lightness is brightness (0–100%). HSV (hue, saturation, value) is similar but uses "value" instead of lightness — common in design software pickers. Our draggable saturation/brightness panel uses HSV internally for natural picker behavior.

CMYK (cyan, magenta, yellow, key/black) is the subtractive model used in printing. Converting RGB to CMYK is an approximation because screen colors are additive while print is subtractive, but the values are useful for print prep and communication with vendors. OKLCH is the newest format worth knowing: based on the Oklab color space, it produces predictable lightness and chroma adjustments — ideal for generating accessible color scales and Tailwind-style ramps.

Below the main swatch, the tool generates tints (mixtures toward white) and shades (mixtures toward black) in ten steps each. Click any swatch to copy its HEX value. Whether you are building a design system, debugging CSS, preparing print assets, or exploring OKLCH for the first time, this all-in-one converter keeps every format in sync from a single source color.

WebColorTools runs entirely client-side — no account, no upload, no server round-trip. Bookmark this page for quick access whenever you need to translate a brand HEX into RGB for a canvas, check CMYK approximations before sending to print, or paste an OKLCH value from a design article into a format your older tools understand.
