You see, a room doused in bright yellow paint hardly ever translates to the happy, lively hue the painter was in search of. It often has the opposite effect--making a space feel muddy and dull. So, being the empowering color that yellow is, it's best used in smaller-scaled doses...scattered throughout a room as an accent. And repetition is absolutely key if you're wanting to accomplish just what you were hoping to with that can of yellow paint. Used smartly, accents of yellow draw you in, and bathe a room in sunshine, which is what most people are searching for in those yellow paint swatches!
