The predominant colors used by Pop Art artists are yellow, red and blue. The colors used were vivid.
I was trying to achieve the 60's feeling by adding Andy Warhol's Marilin image and creating colorful background. I punched some two sized circles from a magazine, then glued them to the cardstock. Next I punched myself a mask ( the same two sized circles) and using a mask I outlined the whole cardstock.
I added Marilyn's quotation and a plastic butterfly to finish my tag.
