Spray paint colours

I’ve just been trying to figure out what colours I need to buy to use in my paintings. I have just sketched this out with pencil so I can get an idea of what to use. The spray paint isn’t cheap so I just wanted to make sure I was buying the correct colours and wanted to try to avoid getting half way through a piece and I needed something else. I have a pink and light blue and very bad quality silver, dark blue, black and white. I don’t really want to use the bad quality again because I think they are too toxic.

From looking at the above drawings I was thinking I need to buy the below:

  • blue or darker blue
  • yellow
  • green
  • black
  • brown
  • red
  • white
  • silver instead of grey

Already have:

  • light pink
  • light blue
