Package javax.vecmath

Class Color4b

All Implemented Interfaces:
Serializable, Cloneable

public class Color4b extends Tuple4b implements Serializable
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.

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.

Java 3D assumes that a linear (gamma-corrected) visual is used for all colors.
