First of all, you have to define what buff is and exactly what red you are using.
Buff can be a very pale yellowish pink. It can also be slightly more orange or brownish yellow. Because all of these contain yellow, I would anticipate that any red you use would become slightly more orange.
The best thing you can do is test it on your pallet, varying the amounts of each color to see what varieties you get.

Males are mostly black and white with some buff coloring on the back of the head and chest. Females are brown and black.
There is not one particular coat color. Colors I have seen include gray, black, buff.
Black is the absence of color, so you cannot make black out of black.

Gibbons tend to be black or buff (a tan-like color). Genetic testing has shown that black is a dominant gene. See the book The Gibbons of Khao Yai: Seasonal Variation in Behavior and Ecology (2009) by Thad Q. Bartlett.
