in my painting class we have to do a self portrait on canvas with acryllic paint using only the primary colors, we can not tint or shade the colors with black or white or use black or white whatsoever. I have done my face and want to do the background next before i do my hair and was thinking possibly doing a hippie pattern background because the background is supposed to reflect who we are. but i worry because hippie patterns are really bright and colorful an i dont want it to over power me in the painting. suggestions? ideas? comments? advise? anything whatsoever can help! please answer! thank you
