Color Format Comparison
**HEX** (#RRGGBB): - 6 characters: #FF5733 - Each pair = Red, Green, Blue in hexadecimal (00-FF) - Most common in web/CSS - Shorthand: #F73 = #FF7733 **RGB** (Red, Green, Blue): - rgb(255, 87, 51) - Each value 0-255 - Light-based (additive color) - Used for screens **HSL** (Hue, Saturation, Lightness): - hsl(9, 100%, 60%) - Hue: 0-360° color wheel - Saturation: 0-100% (gray to vivid) - Lightness: 0-100% (black to white) - Intuitive for adjustments! **CMYK** (Cyan, Magenta, Yellow, Key/Black): - cmyk(0%, 66%, 80%, 0%) - Ink-based (subtractive color) - Used for printing - can't match all RGB colors! **HSV/HSB** (Hue, Saturation, Value/Brightness): - Similar to HSL but different lightness model - Used in design software
How Color Conversion Works
**HEX ↔ RGB** (Easy!): - HEX is just RGB in hexadecimal - #FF5733 = FF(255) 57(87) 33(51) - FF in hex = 255 in decimal **RGB → HSL** (Complex math!): 1. Normalize RGB to 0-1 range 2. Find min/max values 3. Calculate Hue from color ratios 4. Calculate Saturation 5. Calculate Lightness **RGB → CMYK** (Subtractive conversion): - RGB adds light (screen) - CMYK subtracts light (ink) - Formula accounts for different color models - Some colors can't convert perfectly! **Why conversions matter**: - CSS accepts HEX, RGB, HSL - Design tools use different formats - Printers need CMYK - One color, many representations
Color Theory Basics
**Complementary Colors**: - Opposite on color wheel (180° apart) - Red ↔ Cyan, Blue ↔ Orange - High contrast, vibrant combinations - Use for CTAs and emphasis **Analogous Colors**: - Next to each other on wheel - Green, Yellow-Green, Yellow - Harmonious, pleasing to eye - Use for gradients and themes **Monochromatic**: - Different shades of same hue - Vary lightness/saturation only - Professional, cohesive look - Easy to get right! **Triadic**: - Three colors equally spaced (120°) - Red, Yellow, Blue - Vibrant but balanced - Advanced technique **60-30-10 Rule**: - 60% dominant color - 30% secondary color - 10% accent color - Professional design formula
