Changing a Colour Wheel GUI into a colour wheel placed on a part

I am currently working on a easier way to let players pick colours in my game and i’ve found a working colour wheel gui that should work.

the issue is, this gui does not work on a part via surface gui. i’ve looked into the code but i don’t have enough experience to edit the code myself.

here is a link to the colour-wheel i’ve found in the roblox toolbox, credits to @Sub2HTR for making it!

Thank you in advance! i will be sure to credit both the original creator and you when i manage to implement this in-game.
