"Pushing color" is an art expression that describes amping up the intensity (artists call it saturation) of color in a painting. One of the criticisms of the Impressionists, back when they were considered rebels, was that their color was too vibrant.
Saturation has only gone forward from Monet. Intense, vivid color is something contemporary eyes expect. Images in magazines, movies and on television all push color, sometimes to the max. The trick for the artist who also pushes is to keep harmony in the midst of the intensity. If he/she doesn't, it's a discordant confusion. Of course sometimes, that may be exactly what the artist intends.
The pink trees and rainbow sheep above are examples of color pushing that's meant to be harmonious. And though the colors are exaggerated, it was spring, the trees were sort of pink, the sheep sort of glowed.
