Frequently Asked Questions
What colour formats are supported?
HEX (3, 6, and 8-digit), RGB, RGBA, HSL, HSLA, CMYK, HSV, and CSS named colours.
Can I use CSS named colours?
Yes — all 140+ CSS named colours are recognised and converted to HEX, RGB, HSL, and CMYK equivalents.
What is the difference between HSL and HSV?
HSL uses Lightness (50% = pure colour, 100% = white). HSV uses Value (100% = pure colour). Design tools like Photoshop commonly use HSV.
How is CMYK different from RGB?
RGB is additive (for screens). CMYK is subtractive (for print). RGB colours cannot always be exactly reproduced in CMYK print.
Can I get the colour's name?
Yes — if the entered colour matches a CSS named colour exactly, the name is shown.
