You will get an extremely dark brown.
black and orange i think
Black
A very ugly dark brown.
When you mix complimentary colours (colours opposite one another on the colour wheel) you will get a brown or black.
A nondescript brown-black colour that is no use for anything. If you mix all the palette colours together they will always make a sort of poo brown!
dark brown....depends on the quantity of paint use though
Probably a really nasty color.
you gotta mix red with blue to get brown
If you mix a darkish brown with orange and yellow that will be a basic camel colour and then you can lighten it with white or darken it with black gradually until you get the exact colour you wanted. Hope this helped.
