A color that becomes grey has what level of chroma?

When discussing color theory, chroma refers to the purity or intensity of a color. A color that becomes grey indicates that it has been desaturated, meaning the vibrant hue has been muted. This desaturation typically occurs when a color is mixed with its complementary color or with grey, which reduces its brightness and intensity.

In this context, a color that becomes grey can be classified as having low chroma because it no longer retains its strong, vivid qualities. Instead, the grey aspect signifies that the color's purity has diminished, reflecting a lower level of intensity. This aligns with the definition of low chroma, where colors appear more subdued and closer to neutral.

High chroma colors are vibrant and pure, while low chroma colors are washed out or muted, and the grey indicates a significant loss of color vibrancy. Thus, the answer about a color that becomes grey having low chroma is correct, as it appropriately encapsulates the concept of color saturation and intensity.
