Understanding Color Formats
On the web, we have three main ways to describe colors. Each has its own strengths and use cases.
1. HEX (Hexadecimal)
The most common format. Uses 6 characters to represent Red, Green, and Blue values.
#FF57332. RGB (Red, Green, Blue)
Describes colors based on the intensity of light. Great for programmatic color manipulation.
rgb(255, 87, 51)3. HSL (Hue, Saturation, Lightness)
The most human-readable format. Easy to create variations (shades and tints) by just changing the lightness.
hsl(11, 100%, 60%)Basic Color Harmonies
Creating a palette from scratch can be hard. These classic schemes are a great starting point:
- 🌈 Monochromatic: Different shades and tints of the same hue. Safe and professional.
- 🌈 Analogous: Colors that are next to each other on the color wheel. Harmonious and calm.
- 🌈 Complementary: Colors from opposite sides of the wheel. High contrast and vibrant.
- 🌈 Triadic: Three colors equally spaced around the wheel. Bold and balanced.
Color and Accessibility (WCAG)
As a developer, accessibility is your responsibility. The Web Content Accessibility Guidelines (WCAG) require a minimum contrast ratio for text:
- Normal Text (Level AA)4.5:1 ratio
- Large Text (Level AA)3:1 ratio
- Enhanced Contrast (Level AAA)7:1 ratio
