Final answer:
When mixing two primary colors blue and yellow, one can create secondary colors such as green. By blending primary and secondary colors, tertiary hues are produced. The mixture of all primary colors tends to result in neutral colors, but a perfect black is difficult to achieve due to impurities.
Step-by-step explanation:
Secondary colors are produced by mixing two of the primary colors in varying proportions. For instance, mixing blue and yellow produces green, red and blue create violet, and yellow and red make orange. If you mix a primary color with a secondary color, you create what are known as tertiary colors, giving you hues such as red-orange or yellow-green. It's also important to note that mixing all three primary colors tends to yield neutral colors like browns and grays, although a true black is often elusive due to the impurities in subtractive color mixing. When it comes to light, the process is different, known as additive color mixing, using red, green, and blue as the primary colors, where combining all yields white light. In contrast, subtractive color mixing, using primary colors magenta, yellow, and cyan, results in secondary colors with the combination of all three leading to black, theoretically. However, the result is usually closer to brown as true black is hard to achieve because of the mixing impurities.
The primary colors on the color wheel include red, blue, and yellow, which are the foundation for all other colors. Their combinations in different proportions will produce the vast majority of hues we are capable of perceiving.
