Also, in my painting classes I instruct my students to never use black in their paintings. No matter the black that you use–whether lampblack or ivory black or boneblack–the tendency is to use it anytime that you want to make a color darker in value.
You have a much greater variety of color choices when you use other colors to make a color darker.
However, Faber Berrin in his book on color, "The Principles of Light and Color" states that color harmony is achieved by tints -a hue or color with white added, and tone–a hue with black and white added, and shade–a hue with black added, as shown in the chart below.
Some of my favorite artist of the past used black in their paintings with beautiful results.
John Singer Sargent
