Is there any purpose to the color likes and dislikes?

Well I am happy that sims don't react to their favorite colors. They do react to their liked and disliked decor and it can be a bit too much sometimes. They get very tense if they see an item they dislike. I think the buff should have been for multiple decor items, not just one. It's a bit silly to see a sim go up to one candle and react in disgust.
