When only a single color with value is used to create an artwork, the name of the color family is __________________?

A. complementary
B. analogous
C. monocromatic
D. primary

C. monochromatic

C. monocromatic

The answer is C. monochromatic.

To find the answer to this question, you can break it down into parts and analyze each option.

A. Complementary colors are pairs of colors that are opposite each other on the color wheel, such as red and green or blue and orange. This option does not fit the description of using only a single color.

B. Analogous colors are groups of colors that are next to each other on the color wheel, such as blue, green, and yellow or red, orange, and yellow. Again, this option does not fit the description of using only a single color.

C. Monochromatic colors are variations of a single color, achieved by changing its value (lightness or darkness) or saturation (vibrancy or dullness). This option matches the description in the question, as it involves using only a single color with different values.

D. Primary colors are colors that cannot be created by mixing other colors. They are typically red, blue, and yellow. While primary colors are important in color mixing, they do not solely meet the criteria of using only a single color.

Therefore, the correct answer is C. monocromatic, as this option describes the use of a single color with variations in value.
