Of course, not every use of color in Egyptian art was symbolic. When overlapping objects, such as when portraying a row of oxen, the colors of each animal is alternated so as to differentiate each individual beast. Apart from these practical considerations though, it is safe to say that the Egyptian use of color in their art was largely symbolic.
The Egyptian artist had at his disposal six colors, including black and white. These colors were generated largely from mineral compounds and thus retain their vibrancy over the millennia. Each of these colors had their own intrinsic symbolic meaning, as shown below. However, the ambivalence of meaning demonstrated by some should be carefully noted.
