## Frequently asked questions

### Are these color tools free?

Yes. All four tools are free forever, with no account and no limits. Everything runs in your browser, so nothing you pick or convert is uploaded anywhere.

### Which color formats are supported?

HEX (like #3B82F6), RGB (red/green/blue 0-255) and HSL (hue 0-360, saturation and lightness as percentages). The converter moves between all three with input validation.

### What is the contrast checker for?

It tells you whether text in one color on a background of another color meets WCAG accessibility standards: AA and AAA levels for normal and large text. Designers use it to keep text readable for everyone.

### Can I copy the color codes?

Yes. Click any value or swatch to copy it to your clipboard, ready to paste into CSS, design tools or documents.
