Question

How can I convert a RGB color into a HEX in AS3?. For example: R=253 G=132 B=58.

Tks.

Answer 1

Robusto’s solution is too slow.

Because RGB values are stored like this:

8b Red | 8b Green | 8b Blue

And a value of 0-255 (that is not a coincidence) has 8b too, you can use left bitwise shifts to get the int value, and THEN you can get a hex (almost 3 times faster). So:

var intVal:int = red << 16 | green << 8 | blue;
var hexVal:String = intVal.toString(16);
hexVal = "#" + (hexVal.length < 6 ? "0" + hexVal : hexVal);

Where red, green and blue are the values of RGB that you want to convert.
