Turning channels into a HEX code

Each channel from 0 to 255 becomes a two-digit hexadecimal number, padded with a leading zero when needed. Red 37 becomes 25, green 99 becomes 63 and blue 235 becomes EB, producing #2563EB.

When to use which format

HEX is compact and the default in design handoffs.
RGB is easier to tweak channel by channel and supports an alpha value.
HSL is the friendliest when you need a lighter or darker variant of the same hue.

Frequently asked questions

What range do RGB values use?

0 to 255 for each channel. Anything outside that range is clamped automatically.

Can I enter decimals?

Values are rounded to whole numbers because HEX codes only represent integers between 0 and 255.

How do I add transparency?

Copy the RGB value and add an alpha, for example rgba(37, 99, 235, 0.5). An eight-digit HEX also works in modern browsers.

Is the conversion exact?

Yes. Every whole RGB value maps to exactly one HEX pair, with no loss in either direction.
