Chroma Contrast Effect
Posted on 07/06/2012
The chroma contrast effect occurs when a color's chroma is increased or decreased when observed against a background of another color. The general rules are:
1. An object will appear to have a more intense chroma when viewed against a color low in chroma
2. An object will appear to have a less intense chroma when viewed against a color high in chroma
3. The more similar the hue and chroma of the object is to the background color, the less visible the object becomes.
For example, a tooth viewed against a dark orange color background will appear lighter in chroma than the same tooth viewed against a light orange background. This effect is similar to the simultaneous contrast effect noted earlier.
The following illustration* demonstrates the chroma contrast effect.
