Show steps
- Split into pairs: 1F, 8A, 3B.
- Red: 1F = 1 × 16 + 15 = 31.
- Green: 8A = 8 × 16 + 10 = 138.
- Blue: 3B = 3 × 16 + 11 = 59.
How to use the converter
- Type a hex code (#1F8A3B, 1f8a3b or the short form #FA3) or three RGB numbers (31, 138, 59 or rgb(31, 138, 59)).
- Press Calculate or Enter. You get HEX, RGB, HSL and CMYK, a preview, and the contrast with white and black.
How hex to RGB works
Hex is base 16, using the digits 0 to 9 and A to F (A = 10, …, F = 15). Each pair of digits is one color channel from 00 (0) to FF (255). To convert a pair, multiply the first digit by 16 and add the second:
- 1F = 1 × 16 + 15 = 31
- 8A = 8 × 16 + 10 = 138
- 3B = 3 × 16 + 11 = 59
To go back, divide each RGB number by 16: the whole-number part is the first hex digit and the remainder is the second. 138 ÷ 16 = 8 R 10, which is 8A.
