About the Color Converter (HEX, RGB, HSL, CMYK)
A digital color converter translates color codes across different color spaces used in web design, digital graphics, photography, and physical printing. The primary color models are HEX (hexadecimal string), RGB (Red, Green, Blue color channels), HSL (Hue, Saturation, Lightness), and CMYK (Cyan, Magenta, Yellow, Key/Black).
HEX (#RRGGBB) and RGB (0–255) are additive color models designed for luminous electronic displays. HSL represents colors in a manner that mirrors human perception: Hue represents the color wheel angle (0° to 360°), Saturation represents color purity/intensity (0% to 100%), and Lightness indicates luminance from black (0%) to white (100%). HSL makes creating tints and shades intuitive.
CMYK is a subtractive color model designed for commercial ink printing. Because computer monitors display a broader spectrum of vibrant colors (the sRGB/Display-P3 gamut) than physical printing inks can reproduce on paper, converting to CMYK is necessary prior to commercial press production.
The brand blue color HEX #2563EB converts to: RGB(37, 99, 235), HSL(221°, 83%, 53%), and approximate CMYK(84%, 58%, 0%, 8%).
Tips for best results
- Use HSL when designing website UI color scales: keeping Hue and Saturation constant while adjusting Lightness creates perfectly cohesive hover and active button states.
- Always test critical print artwork in a calibrated CMYK color proof, as bright saturated blues and greens on screen often print darker on physical paper.
- Ensure website text meets WCAG AA accessibility standards by maintaining a color contrast ratio of at least 4.5:1 against its background.
