HEX Colors
The most common format for web design. Example: `#3B82F6` (blue)- 6 characters after the # symbol
- Each pair represents Red, Green, Blue (00-FF)
RGB Colors
Used in CSS and digital displays. Example: `rgb(59, 130, 246)`- Three values from 0-255
- Easy to adjust brightness
HSL Colors

Color Harmony Theory

Analogous Colors
Colors next to each other. Harmonious, pleasing to the eye.- Example: Blue + Blue-Green + Green
Triadic Colors
Three colors equally spaced. Vibrant, balanced compositions.- Example: Red + Yellow + Blue
Tips for Choosing Colors
1. Start with one brand color — build your palette around it 2. Use the 60-30-10 rule — 60% dominant, 30% secondary, 10% accent 3. Check accessibility — ensure sufficient contrast for text 4. Test in context — colors look different on various backgrounds
