### Hex-to-RGB Conversion

 JavaScript FAQ | JavaScript Colors FAQ

Question: How do I convert a hex color string (e.g. "FFFFCC") to numeric RGB values?

Answer: Try this script for hex-to-RGB color conversion:   [Looking for RGB-to-Hex?]

 `   ` R: G: B:

The JavaScript source code is simple:

```R = hexToR("#FFFFFF");
G = hexToG("#FFFFFF");
B = hexToB("#FFFFFF");

function hexToR(h) {return parseInt((cutHex(h)).substring(0,2),16)}
function hexToG(h) {return parseInt((cutHex(h)).substring(2,4),16)}
function hexToB(h) {return parseInt((cutHex(h)).substring(4,6),16)}
function cutHex(h) {return (h.charAt(0)=="#") ? h.substring(1,7):h}
```
The script uses a helper function `cutHex()` to check if the `#` character is present in the beginning of the input hexadecimal value. If so, the `cutHex()` function cuts off the `#` so that only the hexadecimal digits are left in the input value. We use the standard JavaScript method `substring()` to get the `R`, `G`, `B` (red, green, blue) hex substrings from the input hexadecimal value. Finally, the script parses the `R`, `G`, `B` values from hexadecimal string to number using the standard function `parseInt(string,16)`; the second argument `16` specifies that the string must be parsed as a hexadecimal (base-16) value.
