[GM-Script-Writer-62850]

seems to work as intended on my end, though it looks like the readme.md file need a update on usage, lacks poll and sync

[GM-Script-Writer-62850]

was looking other some stuff and noticed this:

    rgb = []
    rgb.append(r)
    rgb.append(g)
    rgb.append(b)

    return rgb

you do know you could write that in one short line right? return [r,g,b]

You can refactor that in another patch if you want.

EDIT: Just added it here.
