  7. Well, I also had to fix it, so I fixed the script so it atleast works; and doesn't spit all those errors
  8. The only downside with it is that you can't set the starting color, so it will automatically start as black.

  10. Usage:
  11. colorPicker.openSelect({255,255,255,255}) -- Just to stop it from bugging
