What color results from mixing all three primary colors?

Mixing all three primary colors—red, blue, and yellow—leads to the formation of black. This occurs because combining these colors in equal amounts absorbs most wavelengths of light, resulting in a color that appears black. The process of mixing primary colors can often lead to variations depending on the medium (such as paint, light, etc.), but in the context of subtractive color mixing, the combination of all primary colors generally yields black.

In contrast, gray, brown, and beige arise from different combinations or partial mixtures of colors rather than the complete mixing of all primary hues. Gray is created by mixing black and white, while brown can often be generated by mixing complementary colors or using specific combinations of warm and cool tones. Beige typically results from adding white to brown, making these options less representative of the complete mixture of all primary colors.
