Answer 19

I was just thinking: shouldn't green be separated into it's respective colors?

Answer 20

Actually that's a nice observation considering the rest are prime colors!

Thanks!

Answer 22

Then how would you get a green band?

Answer 23

Blue and yellow mixed make green I think that would be the answer then, considering it's a mixture, see I didn't read the question and jumped to who ever had multiple colors but this is very well true!
