Ebony is a very dark black color with undertones of brown and sometimes olive. Ebonists often use the word ""ebonic"" to describe something that's atypical or different from what one would expect, like an eccentric personality trait! For example: “Ebony Black Coffee,"" sounds strange but after drinking it you'll understand why they say this about their brew. If we were talking piano keys though...the English language owes much thanks for its name derived (""hbn"") which probably comes from Egyptian words meaning 'black'.
