Sims 4 Room Challenge

I make the mistake of picking the wrong colors to build my homes. Then again, in Sims 3 when I had CASt, I went mad with power trying to color code everybody. I ended up with entire towns of sims that wore single-color shirts/blouses and black pants/skirts. In Sims 4 I've tried to avoid it where I can but... well.. I do have a pair of brothers, one wears orange and one wears blue, and their house is almost entirely orange and blue. I may need an intervention.
