Frequently Asked Questions常见问题
What is the difference between HEX and RGB? — HEX is a hexadecimal representation (e.g., #FF5733) while RGB uses decimal values (e.g., rgb(255, 87, 51)). They represent the same color — just in different notations.
What is WCAG contrast? — WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios for text readability: AA Normal (4.5:1), AA Large (3:1), and AAA (7:1). Higher contrast means better readability.
When should I use HSL? — HSL (Hue, Saturation, Lightness) is intuitive for color manipulation. It is easier to create color variations by adjusting saturation or lightness compared to RGB.
