Question

Which of the following is not a primary colour?

• A. Red
• B. Blue
• C. Green
• D. Yellow

Hint:

In the RGB color model, the primary colors are red, green, and blue, while in the traditional RYB model, the primary colors are red, yellow, and blue.

Answer 1

The Correct Option is C

In the context of additive color mixing, the primary colors are red, blue, and green. However, in subtractive color mixing, the primary colors are red, blue, and yellow. Since the question is based on color theory, we know that "Green" is one of the primary colors in the RGB color model (additive color system). But in the traditional RYB model, yellow is considered a primary color.
Thus, the correct answer is (C) Green.
