You can't!
get paint and experiment
If you add red to green, you get brown.
Red and green make an odd sort of brown when mixed together,assuming you mean paint.
There are a lot. For example, I know Purple and Green make it and I think Red and Green.
Hot Pink
Red and green makes brown. Throw in yellow or black to make it lighter or darker. :)
no you'd get brown
It is not possible to make the color brown turn black. Brown is a combination of red, green, and blue hues, while black is the absence of color. Mixing more black paint into brown paint will only darken the shade of brown, not turn it black.
Not if it has enough pigment in it.
If you mix red and green paint you get brown.
Add white paint.
You can make brown paint with a bit of blue and lots of red and yellow. (the primary colours). To make brown with a tint of red, you just add more red depending on how red you want your brown. If that makes sense.
