| Lime Material. Place a piece of lime material by clicking on the lime Material button and then clicking in either the Material A Region or the Material B Region. To see how the percentage of incident light reflected by lime material varies by color, click the Open Material A Graph or Open Material B Graph buttons. To see the spectrum of light from a particular source reflected by lime material, use the Spectroscope tool. To model the reflection by a "perfectly" lime material, use the Ideal Material tool.
