Class Color

java.lang.Object
  org.jzy3d.colors.Color

public class Color
extends java.lang.Object

Color provides a representation of a color. The color representation relies on a set of float components with values in the range [0;1]. When using the integer constructor of Color, values are expected to stand in [0;255] and are scaled to be maintained in [0;1] afterward. Beside being a convenient container, Color also:

• can easily provide its negative()
• can easily provide its representation as a float array through toArray()
• can provide its hexadecimal string representation with toHex()
• can return an AWT equivalent with awt(), and be built with a constructor supporting an AWT color.
• can generate random() colors.
