I think brown is a very underrated color, maybe because it is somewhat subtle and commonplace it is easily overlooked, but it's the color of some of my favorite things:

Chocolate, coffee, many soft furry animals, wood furniture, the prettiest hair and eyes...

I love how warm and naturalistic the color is, instantly giving a feeling of coziness and comfort.

Color psychology associates the color brown with qualities such as earthiness, simplicity, appreciation, warmth, protection, groundedness, honesty, comfort, stability, resilience, and wisdom.
