HEX to RGB Converter

A hex code is three numbers written in base 16, two characters each. Read each pair, convert it from base 16 to decimal, and you have the red, green and blue amounts. #5B8DEF splits into 5B, 8D and EF, which are 91, 141 and 239. Written the way code expects it, that is rgb(91, 141, 239).

Nothing is lost in the conversion: hex and RGB hold the same 16.7 million colors. The only difference is notation, which is why hex and RGB are interchangeable rather than two different color models.

Canvas and WebGL drawing calls take three separate numbers. Many charting libraries, PDF generators and email builders take channel values rather than hex strings. Building a transparent overlay usually means writing rgba(91, 141, 239, 0.4), which needs the RGB channels plus an alpha value - a hex code alone cannot express that in older email clients.

RGB is also the form you need when you are computing rather than styling: averaging two colors, lightening a channel, checking luminance for a contrast ratio, or generating a gradient by stepping between two triples. All of those operations happen on the three channels, so start from RGB.

Short hex codes expand before converting. #FC0 is #FFCC00, so its RGB is 255, 204, 0 - not 15, 12, 0. Huevex expands short codes for you, so pasting either form gives the same result.

Hex and RGB both describe sRGB light, not ink. If the value is going to print, convert to CMYK instead and expect to proof it, because the same number printed on coated and uncoated stock will not match the screen.
