Color Theory: Mixing Paint Colors : Color Theory: Pigment Strength

[KevinMcCainStudios]

Black doesn't necessarily makes colors muddy,no more than green or voilet, it how you use black, which kind of black, which type of colors they are mixed in. How clean your brush is and so forth. Black used correctly is a beautiful color. Most of the Great Masters over the last 600 years have used black.

You would mix nicer colors if you used the complementray color to darken your color, black makes things look "muddy"
