Frequently asked questions
What range do the RGB values use?
Each channel goes from 0 to 255, the standard 8-bit range for sRGB colors. The tool converts each value to its two-digit hexadecimal equivalent.

Can I get a shorthand 3-digit hex?
Only when each channel's two digits are equal (e.g.
Is my data sent to any server?
No. The conversion is mathematical and happens entirely in your browser.
When should I use hex instead of RGB?
Hex is compact and the most common format in CSS and design tools. RGB is handier when you compute values programmatically or need to add an alpha channel.
