Walnut brown — Walnut Brown belongs to the Brown family, with strong ties to Gray. This is a deep, earthy brown with a pronounced grayish tone, similar to the color of wet river clay or a dark, weathered stone. It is in the Brown family because its hex code has a dominant, but low-valued, red and green mix that creates a deep, warm, and desaturated tone. The nearly equal distribution of all three values gives it a distinct grayish appearance. Its nearest neighbors are a similar dark gray-brown (#544D42), a classic Dark Brown (#654321), and a darker gray-brown (#45433B).
