This doesn't mean that yellow can't be used for dark art. It's just that you should first explore commonly used color combinations. I hope this has helped you at least a little (*´ . ｀*)

Maybe you should observe different seasons, times of day, and so on. Take more photos of nature. Yes, it sounds terribly corny, haha. You can also study other works of art. Let's say we have yellow. Yellow at sunset adds a cozy and warm atmosphere.
