One thing I find myself doing often is picking out color schemes in my surroundings. I'll do it anywhere, from random buildings to plants to bathrooms. It's a hobby. I've been favoring these colors the most lately. I think they're particularly inspired by a series of four paintings in the Kimbell, but they're also the shades I find myself incorporating in my own details more often. Super bright reds and mustard yellows are perfect accents, and dark, elegant shades and pale colors are staples.
Try to pick out nice color schemes around you, wherever you are. It's a lot of fun, and you might find inspiration that way!
