HEX to RGB Converter

A hex color code is just three numbers — red, green, blue — each written as two hexadecimal (base-16) digits. Converting to RGB means reading each pair as a normal decimal number from 0 to 255.

1. Remove the #. #2D56A3 → 2D56A3. For 3-digit shorthand, double each digit: #F80 → FF8800.
2. Split into pairs. Red 2D, green 56, blue A3.
3. Convert each pair. First digit × 16 + second digit, where A = 10, B = 11, C = 12, D = 13, E = 14, F = 15.
   2D = 2 × 16 + 13 = 45 · 56 = 5 × 16 + 6 = 86 · A3 = 10 × 16 + 3 = 163
4. Write it as RGB. #2D56A3 = rgb(45, 86, 163).

Going the other way: RGB to HEX

Divide each channel by 16: the quotient is the first hex digit, the remainder the second. rgb(194, 66, 66) → 194 = 12×16 + 2 → C2, 66 = 4×16 + 2 → 42, giving #C24242. The dedicated RGB to HEX converter does this for you.

Alpha, 8-digit hex and other notations

An 8-digit code like #3E2608FF adds a fourth pair for alpha: divide it by 255 to get the RGBA alpha (FF → 1, 80 → 0.502). Programming languages often write hex with a 0x prefix, and Android/.NET put alpha first (0xAARRGGBB). All of these work in the converter. More in the RGBA & transparency guide and the CSS color formats reference.

In code

// JavaScript
const hexToRgb = hex => {
  const n = parseInt(hex.replace('#', ''), 16);
  return [n >> 16 & 255, n >> 8 & 255, n & 255];
};
hexToRgb('#2D56A3'); // [45, 86, 163]

# Python
def hex_to_rgb(h):
    h = h.lstrip('#')
    return tuple(int(h[i:i + 2], 16) for i in (0, 2, 4))
