Learn how to manually convert values between RGB color and hexadecimal numbering system.
How RGB to Hex Conversion Works
RGB (Red, Green, Blue) colors use decimal values from 0-255 for each channel. Hexadecimal color codes represent these same values in base-16 notation, where each color channel is represented by two hex digits (00-FF).
Conversion Process:
- Take each RGB value (0-255)
- Convert to hexadecimal (00-FF)
- Concatenate in order: RRGGBB
- Add # prefix for CSS/HTML use
Example:
RGB(255, 99, 71) → #FF6347 (Tomato Red)
- Red: 255 → FF (15×16 + 15 = 255)
- Green: 99 → 63 (6×16 + 3 = 99)
- Blue: 71 → 47 (4×16 + 7 = 71)
