Frequently Asked Questions
How do I convert RGB to HEX?
Convert each RGB value (0-255) to a 2-digit hexadecimal number and concatenate them with a # prefix. For RGB(255, 128, 0): 255=FF, 128=80, 0=00, so HEX is #FF8000.
Why use HEX instead of RGB in CSS?
HEX codes are more compact (7 characters vs ~16 for rgb()) and are widely recognized by designers. However, RGB is easier to read and modify. Both are fully supported in modern CSS.
