In order to do the 3d color wheel, I did a little math first and cut out all the material (color aids and paper board and sticks) I need before I put them together.
Then I stated to put them together
This is the finished piece
For Painted Color Chart I first cut out the color aids.
I experimented different kinds of combinations to make sure the color matched the color aids.
this is the finished piece with two ratio chart(the upper one is the successful one, and the lower is the failed)
