Color Converter

The color converter reads a color value entered in any of five formats, HEX, RGB, HSL, HSV, or CMYK, and returns the same color expressed in all five at once, with a live preview swatch. Format is detected automatically from the value entered, so no format needs to be chosen in advance.

HEX packs a color into a six-digit (or shorthand three-digit) hexadecimal code, where each pair of digits, 00 to FF, is the red, green, or blue channel expressed as a value from 0 to 255. RGB states those same three channels directly as decimal numbers from 0 to 255. HSL and HSV both describe color by hue, a position from 0 to 360 degrees around the color wheel, and saturation, but the third value differs: HSL uses lightness, how close the color sits to black or white, while HSV uses value (or brightness), how close it sits to black alone. CMYK is the subtractive, ink-based model used in print, giving cyan, magenta, yellow, and key (black) as four percentages that describe how much of each ink lands on white paper; more ink darkens the result, the opposite of how RGB and HSL/HSV behave on a screen.

HEX values may be shorthand (#F53) or full (#FF5733), with or without the leading hash. RGB accepts the wrapped form, rgb(255,87,51), or bare comma-separated channels, 255,87,51. HSL and HSV follow the same pattern, hsl(11,100%,60%) or hsv(11,100%,100%), with the percent signs optional. CMYK accepts cmyk(0,66,80,0) or four bare comma-separated percentages.

Any of the five output values can be copied directly to the clipboard for use in CSS, design software, or documentation, and the preview swatch shows the resulting color at a glance. Settings holds display options for the HEX output: uppercase or lowercase letters, and whether the leading # is included.

Color conversion supports a wide range of creative and technical workflows. Designers, developers, and print professionals routinely translate colors between models for consistency across screens, browsers, and printed materials. Quick conversion replaces manual calculation and lookup tables, producing every major format in a single step.

• Web Development: Convert a brand color from a HEX code provided by a designer into RGB or HSL for use in CSS custom properties, gradients, and animations where HSL manipulation is more intuitive.
• Graphic Design: Translate a screen color from RGB or HSL into CMYK before sending artwork to a commercial printer, helping the printed output match the on-screen design as closely as possible.
• UI/UX Design: Build harmonious palettes by adjusting hue, saturation, and lightness in HSL or HSV, then convert the results to HEX for implementation in design tokens and component libraries.
• Brand Identity: Maintain a brand style guide that lists every official color in HEX, RGB, HSL, and CMYK so that marketing teams, developers, and print vendors all work from the same source of truth.
• Accessibility Testing: Convert colors to RGB values needed by contrast ratio tools to verify that text and background combinations meet WCAG guidelines for readability.
• Game Development: Translate HSV values used in color picker interfaces inside game engines into HEX or RGB for shader code and asset configuration files.
• Data Visualization: Define a base color in HSL, adjust lightness programmatically across data categories, and export the final palette in HEX for charting libraries.
• Print Production: Verify CMYK breakdowns for spot color approximations when Pantone matching is unavailable, converting from the original digital HEX specification to the four-channel print model.
