What is the key difference between primary and secondary colors?

• A. Primary colors are softer than secondary colors
• B. Secondary colors can be created by mixing primary colors
• C. Primary colors can be mixed to create secondary colors
• D. Secondary colors come from natural pigments

Answer: (C)

The main idea is how colors relate as building blocks. Primary colors are the base hues you can’t create by mixing other colors, and secondary colors are what you get when you mix two of those primaries. That’s why this statement is the best: it describes the process by which secondary colors are formed from the primaries. For example, mixing red and yellow yields orange, yellow and blue yield green, and blue and red yield purple. This shows primaries as the source colors and secondaries as their mixtures.
