/**
 * 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.
