Which of the following combinations represents the secondary colors?

The correct combination that represents the secondary colors is green, orange, and violet. In color theory, secondary colors are created by mixing two primary colors together. The primary colors are red, blue, and yellow. When you mix these primary colors, you achieve the following secondary colors:

• Mixing red and yellow yields orange.
• Mixing blue and yellow results in green.
• Mixing red and blue produces violet.

By understanding this concept, it's clear that the combination of green, orange, and violet accurately represents the secondary colors formed from primary colors. The other choices do not fit the definition of secondary colors as they either list primary colors, unrelated colors, or neutrals, which are not categorized as secondary.
