I did think I understood what you wrote. If you compare all three side by side in person, the difference brown and black & black's variants is clear. Pun intended. If I didn't want a pun, I would have said obvious instead of clear.

Describing color variations in words is by definition a difficult task. Colors are seen not read, and words can only inexactly symbolize colors.

In short "Seeing is believing."
