Color Converter FAQ and Usage Guide
What are HEX, RGB, and HSL?
Three main ways to represent colors on the web:
- HEX: Hexadecimal color code (e.g., #3b82f6)
- RGB: Red, Green, Blue values (0-255)
- HSL: Hue, Saturation, Lightness
What is Contrast Ratio?
The ratio of brightness difference between foreground (text) and background colors. Higher ratios are easier to read and required for WCAG (Web Content Accessibility Guidelines) compliance.
What are WCAG levels?
- AAA (7:1 or higher): Highest accessibility, easy to read for all users
- AA (4.5:1 or higher): Standard accessibility, recommended for most websites
- Fail (below 4.5:1): Does not meet accessibility standards
Large text (18pt or larger) only needs 3:1 for AA level.
When to use which color format?
- HEX: Most commonly used in CSS
- RGB: Convenient for color manipulation in JavaScript
- HSL: Useful for creating color palettes, adjusting brightness/saturation
