Which primary color combines with yellow to create green?

1. Blue

2. Red

3. Cyan

4. Orange

The correct answer is: Blue

The primary color that combines with yellow to create green is blue. In color theory, specifically under the subtractive color model (often used in painting and printing), yellow and blue are two of the three primary colors. When mixed together, they create green, which is known as a secondary color. In this context, the mixing of these colors follows the principle that primary colors cannot be created by mixing other colors together, but when you combine them, you can produce secondary colors. Yellow and blue are crucial examples of this process, demonstrating how two primary colors interact to form a completely different hue. Other choices such as red, cyan, and orange do not participate in the formation of green when paired with yellow. Red is a primary color but does not mix with yellow to create green. Cyan is actually a secondary color created by mixing green and blue, while orange is another secondary color formed by mixing yellow and red. Therefore, blue stands out as the only correct choice in this scenario.
