When Blue and Yellow are mixed, which color is produced?

• A. Orange
• B. Green
• C. Violet
• D. Brown

Answer: (B)

Mixing blue and yellow pigments uses subtractive color mixing. In pigments, primary colors are red, blue, and yellow; when you blend two primaries, you get a secondary color. Blue pigment reflects blue light, while yellow pigment reflects red and green light. The combination ends up reflecting mainly green light, so the resulting color is green. (If you were mixing colored light instead of pigments, blue and yellow light would move toward white, but that’s not the context here.)
