In German class, they had a question about mixing all colors together, and what color do they make:
a) brown
b) black
c) gold
d) white
As a artist and designer, I can tell you that it's definitely not gold.
They were looking for black of course; I guessed that's what they wanted.
However, everything but gold is technically correct, in different circumstances (which they did not specify).
Paint: A shade of brown
Print: Black (technically, sorta; this is why there's K in CMYK)
Screen: White
