What does red and red and red make?

If you are using paint then you would just get a big blob of red paint. Or if you are using pencil crayons then it would just look like red. It would look like a solid colour. Or if you are using crayons, then it would be the same thing, and so it would be for the chalk. If you are using it. Either way you just end up with red. The colour only changes if you add another colour. Hope this helps anyone, and if im wrong sorry.
