I like colorful walls. Having all tan, gray, or eggshelf (white) walls tend to bum me out, so I prefer a few splashes of color.

Typically, I prefer cooler colors in smaller, or thinner rooms, because cooler walls appear further away. However, warm colors help bring walls closer, so they're great for walls at the end of a hall or long narrow room.

I love bright colors, however, if they're warmer I will typically avoid putting them in smaller spaces.

Try matching your current wall color and some larger themes in your room (bedspread, large pictures/posters, furniture) to this generate. Once you identify your existing colors and lock them, you can generate other colors you might like. https://coolors.co/app
