The three primary colors are red yellow and blue, so the only option that would work would be yellow! I hope this helps! :)
Contrast: The work in today's art is a lot more advanced. Prehistoric people were simple and didn't use the major fundamentals of art. They're work is really abstract and really only consisted of warm colors and black.
Compare: Like some of today's artists, some of the prehistoric painting tell stories, or describe ones feelings.
Hope that helps!!! <span />
this is the possible answer I could think of hope it help though :))))
