Frequently Asked Questions

What is the difference between HSL and HSV?
Both describe color as hue, saturation, and a third value. HSL uses Lightness (0% black → 100% white). HSV uses Value/Brightness (0% black → 100% pure color). HSL is more common in web design; HSV is common in image editors.
When should I use CMYK?
CMYK is the subtractive color model used for print. If you are sending a brand color to a print shop, give them the CMYK values. For screens, stick to HEX/RGB/HSL.
Are 8-digit HEX colors widely supported?
Yes. Every modern browser supports `#RRGGBBAA` (HEX with alpha). For older environments, use `rgba()` instead.
Is the color picker accurate?
The picker uses the browser's native color picker for accuracy, and outputs match the standard sRGB color space.
Does it work offline?
Yes. All conversions are computed locally in your browser.
