Study Notes
CSS Color Representation
- CSS supports 140 predefined color names (e.g., blue, red)
- While valid, these names lack the precision of other methods like RGB and Hex.
- RGB (Red, Green, Blue) represents colors by combining the intensity of red, green, and blue light.
- Each component ranges from 0 to 255 (8 bits).
- Possible color combinations: 256 x 256 x 256 = 16,777,216
- RGB examples:
- Black: rgb(0, 0, 0)
- White: rgb(255, 255, 255)
- Red: rgb(255, 0, 0)
- Green: rgb(0, 255, 0)
- Blue: rgb(0, 0, 255)
- Orange: rgb(255, 128, 0)
- Turquoise: rgb(72, 209, 204)
Hexadecimal Codes
- Hex codes compactly represent RGB colors in CSS using a base-16 system.
- Hex digits: 0-9 and A-F (A=10, F=15)
- Example conversions:
- rgb(255, 0, 0) = #FF0000 (red)
- rgb(0, 255, 0) = #00FF00 (green)
- rgb(0, 0, 255) = #0000FF (blue)
- CSS usage:
p { color: #FF8000; }
Abbreviated Hex Codes
- Shorthand hex notations are possible if pairs of hex digits are identical.
- Examples:
- #FFF = #FFFFFF (white)
- #000 = #000000 (black)
- #0F0 = #00FF00 (green)
- #ABC = #AABBCC
- Recommendation: Use full 6-digit hex codes for clarity.
Practical Usage
- Color pickers help convert between RGB and hex color values.
- Example: RGB (72, 209, 204) equals #48D1CC (turquoise).
