Which color is one of the additive primary colors?

• A. Yellow
• B. Cyan
• C. Green
• D. Magenta

Answer: (C)

Additive color mixing deals with light, and the primary colors of this system are red, green, and blue. When you combine these bright colors, you add light to produce other colors, and mixing all three at full intensity gives white. Among the options, green is one of these true additive primaries. The others are blends: yellow is red plus green light, cyan is green plus blue light, and magenta is red plus blue light. So green is the correct additive primary color.
