?Frequently Asked Questions
What is WCAG contrast and why does it matter?
WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios for text readability. Normal text needs 4.5:1 contrast ratio (AA level), large text needs 3:1. This ensures people with visual impairments can read your content. Failing contrast = excluding users.
What's the difference between RGB and HSL?
RGB (Red, Green, Blue) defines colors by mixing light. HSL (Hue, Saturation, Lightness) is more intuitive: Hue is the color (0-360°), Saturation is intensity (0-100%), Lightness is brightness (0-100%). HSL makes it easier to create variations of a color.
How do HEX codes work?
HEX codes are RGB values in hexadecimal. #FF5733 = FF (255 red), 57 (87 green), 33 (51 blue). Each pair is 00-FF (0-255 in decimal). Shorthand #F53 expands to #FF5533.
Can I save color palettes?
You can copy any color value or gradient CSS code. For saving palettes, consider using the copied values in a design tool like Figma, or create a CSS file with your color variables.
