Frequently Asked Questions
What is the difference between HEX, RGB, and HSL?
HEX is hexadecimal shorthand for red, green, and blue values. RGB defines colors as 0-255 values per channel. HSL defines Hue (angle), Saturation (percentage), and Lightness (percentage), making it intuitive for human design adjustments.
What WCAG contrast ratio is required for text?
WCAG 2.1 AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (18pt or bold 14pt). AAA compliance requires 7:1 for normal text.
Can I copy color values directly into CSS?
Yes. Click any color format card (HEX, RGB, HSL) to copy the exact CSS-ready declaration directly to your clipboard.
