Frequently Asked Questions
How does HEX to RGB conversion work?
A HEX color code is RGB values written in base-16. #1A2B3C splits into #1A (R), #2B (G), #3C (B). Convert each pair from hex to decimal: 1A = 26, 2B = 43, 3C = 60. So #1A2B3C = rgb(26, 43, 60).
What is the difference between 3-digit and 6-digit HEX?
3-digit HEX (#RGB) is shorthand for 6-digit — each digit is doubled. #ABC = #AABBCC. It only works when both digits of each pair are identical. #FFF = #FFFFFF (white).
When do I need RGB instead of HEX?
Use RGB when working with CSS rgba() for transparency, Canvas 2D context fillStyle, WebGL, three.js, image processing libraries (sharp, Pillow), and any API requiring decimal color values rather than hexadecimal.
Is my data stored?
