Which one of the following is known as a primary color?

The concept of primary colors is essential in color theory, particularly in the context of art and design. Primary colors are defined as colors that cannot be created by mixing other colors together; they serve as the foundation for creating a broad spectrum of other colors.

In the traditional color wheel, which is based on the subtractive color mixing model (often associated with painting), the primary colors are blue, red, and yellow. These colors can be mixed in various combinations to produce a range of secondary colors (such as green, orange, and purple, which are created by mixing primary colors).

In this context, red is recognized as one of the primary colors because it cannot be derived from the combination of other colors. Instead, it plays a central role in creating various shades and hues by mixing it with primary blue and yellow. The understanding of primary colors forms the building blocks for color mixing and is crucial for anyone working in fields involving aesthetics, such as art, design, and esthetics.
