How to convert RGB to hex
Each RGB value is a number from 0 to 255. Divide it by 16: the whole-number result is the first hex digit and the remainder is the second. Write 10 to 15 as A to F, then join the three pairs after a #.
172 ÷ 16 = 10 remainder 12, so A and C = AC
247 ÷ 16 = 15 remainder 7, so F and 7 = F7
66 ÷ 16 = 4 remainder 2, so 4 and 2 = 42
Result: #ACF742
Values below 16 need a leading zero, so 5 becomes 05 and rgb(5, 5, 5) becomes #050505.
RGBA to hex
For transparency, multiply the alpha (0 to 1) by 255, round it, and add it as a fourth pair. rgba(172, 247, 66, 0.5) gives 0.5 × 255 = 127.5, which rounds to 128, or 80 in hex: #ACF74280. Type the alpha in the converter’s Alpha box and it adds that pair for you.
Tip: you can paste a whole value like rgb(172, 247, 66) into any of the three boxes and the converter fills all of them.
