In color theory, what does 'value' refer to?

In color theory, 'value' specifically refers to the lightness or darkness of a color. This concept is fundamental because it determines how a color will appear in relation to others and affects the overall composition of a design. Light values, often referred to as tints, are created by adding white to a color, making them lighter, while dark values, known as shades, result from adding black to a color, making them darker.

Understanding value is crucial in floral design as it helps in creating depth, contrast, and visual interest. For instance, a bouquet that effectively uses a range of values can create a striking composition that draws the viewer's eye.

The other options touch on different aspects of color but do not define 'value'. The strength of a color relates more to its intensity or saturation. The type of color scheme refers to the grouping of colors that create harmony or contrast in a design. Finally, saturation specifically addresses the purity or intensity of a color rather than its lightness or darkness. Therefore, 'value' as lightness or darkness is the correct interpretation within the context of color theory.
