About Color Converter (HEX, RGB, HSL, CMYK)
Color spaces serve different domains of digital graphics, UI development, and physical print production. The sRGB color model, foundational to web browsers, defines colors through additive red, green, and blue light components ranging from 0 to 255 (or expressed as 6-digit hexadecimal triplets). HSL (Hue, Saturation, Lightness) and HSV (Hue, Saturation, Value) reorganize these coordinates into cylindrical geometries that are far more intuitive for human designers to adjust luminosity, pastel tints, and vibrant accent harmonies without changing the underlying base hue. Conversely, CMYK (Cyan, Magenta, Yellow, Key/Black) represents a subtractive four-color printing model where pigments absorb light rather than emit it. Converting from additive RGB to subtractive CMYK requires calculating the black key component (K = 1 - max(R,G,B)) followed by chromatic ink densities. This browser tool carries out exact floating-point conversions and evaluates relative luminance to test WCAG 2.1 compliance.
