Which colors are considered the three pure primary colors?

• A. Red, Blue, and Yellow
• B. Red, Green, and Blue
• C. Green, Blue, and Yellow
• D. Red, Violet, and Yellow

Answer: (A)

In pigment color theory, the three pure primary colors are red, blue, and yellow. These are considered primaries because they can’t be created by mixing other pigments, and they serve as the building blocks to make all other colors through mixing. Green is a secondary color formed by mixing blue and yellow, so it isn’t one of the primaries. Violet (purple) is produced by mixing red and blue, also not a primary. The option that lists red, blue, and yellow matches the traditional pigment primaries, which is why it’s the best choice. (Note: different contexts, like light-based color, use red, green, blue as primaries, or cyan, magenta, yellow for printing, but for pigments the classic trio is red, blue, and yellow.)
