Color converter, every notation, both directions.

Hexadecimal color is just base-16 notation for the red, green and blue channels. The code #845EC2 splits into three pairs: 84 for red, 5E for green and C2 for blue. Convert each pair to decimal — 84 becomes 132, 5E becomes 94 and C2 becomes 194 — and you have rgb(132, 94, 194). Shorthand hex like #abc expands to #aabbcc before the same conversion.

Going the other way divides each channel by 16 and writes the quotient and remainder as hex digits: 132 is 8×16 + 4, so it becomes 84, and values below 16 need a leading zero. This converter does that two-way math live for every field — type in any format and all six models update together, so you never lose the value you started with.

HEX is the compact standard for CSS, design tools and anywhere a color travels as a short string. RGB mirrors how screens emit light and is the right choice when you need alpha transparency as rgba(). HSL — hue, saturation, lightness — is the most intuitive model for editing: keep the hue, move one slider to generate tints and shades systematically.

HSV works similarly for pickers, CMYK describes subtractive ink for print (conversions from sRGB are approximations, not color-managed proofs), and OKLCH is the perceptually uniform next generation built into modern CSS: equal lightness steps look equally light, which makes palettes far easier to balance.
