What term describes colors produced by combining red, green, and blue light?

• A. Additive primaries
• B. Subtractive primaries
• C. Secondary colors
• D. Complementary colors

Answer: (A)

Additive color mixing is at work when colors are produced by combining red, green, and blue light. These three colors are the primaries in this system, and mixing them in different proportions creates other colors; all three together at full intensity yield white. For example, red plus green makes yellow, red plus blue makes magenta, and green plus blue makes cyan. Subtractive primaries describe pigment mixing, not light, and secondary colors are what you get when you mix two primaries, while complementary colors are opposite pairs that balance each other. So the colors produced by combining red, green, and blue light are additive primaries.
