Frequently Asked Questions
How do I convert HEX to RGB manually?
Split the 6-digit HEX code into 3 pairs and convert each pair from hexadecimal to decimal. For #FF5733: FF = 255, 57 = 87, 33 = 51, giving RGB(255, 87, 51). Each hex digit represents 0-15, so "FF" = 15×16 + 15 = 255.
What is a 3-digit HEX color code?
A 3-digit HEX code is shorthand for 6-digit codes where each pair of digits is identical. #FFF is shorthand for #FFFFFF (white), #000 for #000000 (black), #F60 for #FF6600. CSS accepts both 3-digit and 6-digit HEX codes.
What is RGBA and how is it different from RGB?
RGBA adds a fourth channel — Alpha — for transparency. Alpha values range from 0 (fully transparent) to 1 (fully opaque). CSS syntax: rgba(255, 87, 51, 0.5) creates a semi-transparent color. Modern CSS also supports 8-digit HEX codes with alpha: #FF573380 (the last two digits are the alpha).
