Mike,

Can you explain more of what this does and when it might be used?

From what I can tell it allows the ability to choose a foreground color (and it could easily be adapted to background color also) while in the middle of running a script vs waiting until the script finishes.

Right, it lets the user pick a color in an interface they are used to while the script is running.

The function can be changed so it returns the color instead of setting the foreground so the color can be used for anything.

Great, thanks. I will probably find some fun uses for this.
