Frequently Asked Questions

What is the difference between RGB and CMYK?

RGB is an additive color model used for electronic screens (monitors, phones), while CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive model used for physical printing.

How is WCAG color contrast calculated?

Contrast is measured based on relative luminance between foreground and background. WCAG AA requires a minimum ratio of 4.5:1 for normal text and 3.0:1 for large text.

Can I input CSS named colors like 'indigo' or 'coral'?

Yes! The parser supports all 140+ standard W3C CSS named color keywords and converts them immediately to HEX, RGB, HSL, and CMYK.

Is my palette saved on any server?

No. All color math, harmony generation, and conversions happen 100% locally in your browser memory.
