Which of the following represents secondary colors?

Secondary colors are created by combining equal parts of two primary colors. In the color theory, the primary colors are red, yellow, and blue. When these primary colors are mixed, they produce three secondary colors: orange (from red and yellow), green (from yellow and blue), and violet (from red and blue).

The correct answer encompasses these combinations by identifying orange, green, and violet as the secondary colors derived from the mixing process. Understanding this concept is crucial for nail technicians, as color mixing can impact nail art and design, enabling them to achieve a wide spectrum of shades for their clients.

The other choices include primary colors or variations of tertiary colors rather than strictly secondary colors, which clarifies why they do not accurately fit the definition provided.
