Question 79

Blue is a primary color.

Primary colors are the foundational colors that can be combined to create a broad spectrum of other colors. In the context of traditional color theory, blue is recognized as one of the three primary colors.

A) White

White is not a primary color; rather, it is the result of combining all colors of light. In pigment terms, it is often considered the absence of color or the color of a surface that reflects all wavelengths of light.

B) Blue

Blue is a primary color in both additive and subtractive color models. It cannot be created by mixing other colors and serves as a fundamental building block for creating a wide variety of other colors in various color mixing contexts.

C) Black

Black is not a primary color; in color theory, it is often seen as the absence of color or the result of combining multiple colors in pigment. It is not a foundational color that can be used to create other colors.

D) Green

Green is not a primary color; it is a secondary color made by mixing the primary colors blue and yellow. While it is a significant color in the color spectrum, it does not serve as a foundational color on its own.

Conclusion

Blue is definitively the correct answer as it is recognized as a primary color that cannot be formed by mixing other colors. The other options, white, black, and green, either represent combinations of colors or are secondary colors, thus failing to meet the criteria for primary colors.
