/**
* A four-byte color value represented by byte x, y, z, and w values. The x, y,
* z, and w values represent the red, green, blue, and alpha values,
* respectively.
* <p>
* Note that Java defines a byte as a signed integer in the range [-128, 127].
* However, colors are more typically represented by values in the range [0,
* 255]. Java 3D recognizes this and for color treats the bytes as if the range
* were [0, 255]---in other words, as if the bytes were unsigned.
* <p>
* Java 3D assumes that a linear (gamma-corrected) visual is used for all
* colors.
