Red, yellow, and blue may be the preferred color scheme for the 5-and-under set, but that doesn't mean that the heart of the color wheel is lacking in sophistication. Artists of the De Stijl movement in the 1920s including Piet Mondrian and Gerrit Rietveld, which also influenced members of the Bauhaus, were so enamored of primary colors that they restricted their palette to only red, yellow, blue, black, white and gray.
While I freely admit that primary colors can evoke a kindergarten or (worse) the 80s, they can also be classic, playful, modern and absolutely all grown-up.
