Mr/Mrs Client,
As I understand it, you need an ahk script that can recognize color.
AHK has built-in fuctions to find pixels of certain colors on a screen.
Depending on your needs, this function could be enough, or if your needs
are more complex, then more advance algorithms need to be used.
As such, could you share some further information as to where
you plan to use the script?
Best Regards,
Hilmi
