  41  * The Color class is used to encapsulate colors in the default sRGB color space.
  42  * Every color has an implicit alpha value of 1.0 or an explicit one provided
  43  * in the constructor. The alpha value defines the transparency of a color
  44  * and can be  represented by a double value in the range 0.0-1.0 or 0-255.
  45  * An alpha value of 1.0 or 255 means that the color is completely opaque
  46  * and an alpha value of 0 or 0.0 means that the color is completely transparent.
  47  * When constructing a {@code Color} with an explicit alpha or getting
  48  * the color/alpha components of a Color,
  49  * the color components are never premultiplied by the alpha component.
  50  *
  51  *
  52  * <p>{@code Color}s can be created with the constructor or with one of several
  53  * utility methods.  The following lines of code all create the same
  54  * blue color:</p>
  55  *
  56  * <pre><code>
  57  * {@literal
  58  * Color c = Color.BLUE;   //use the blue constant
  59  * Color c = new Color(0,0,1,1.0); // standard constructor, use 0->1.0 values, explicit alpha of 1.0
  60  *
  61  * Color c = Color.color(0,0,1.0); //use 0->1.0 values. implicit alpha of 1.0
  62  * Color c = Color.color(0,0,1.0,1.0); //use 0->1.0 values, explicit alpha of 1.0
  63  *
  64  * Color c = Color.rgb(0,0,255); //use 0->255 integers, implicit alpha of 1.0
  65  * Color c = Color.rgb(0,0,255,1.0); //use 0->255 integers, explicit alpha of 1.0
  66  *
  67  * Color c = Color.hsb(270,1.0,1.0); //hue = 270, saturation & value = 1.0. inplicit alpha of 1.0
  68  * Color c = Color.hsb(270,1.0,1.0,1.0); //hue = 270, saturation & value = 1.0, explicit alpha of 1.0
  69  *
  70  * Color c = Color.web("0x0000FF",1.0);// blue as a hex web value, explicit alpha
  71  * Color c = Color.web("0x0000FF");// blue as a hex web value, implicit alpha
  72  * Color c = Color.web("0x00F");// blue as a short hex web value, implicit alpha
  73  * Color c = Color.web("#0000FF",1.0);// blue as a hex web value, explicit alpha
  74  * Color c = Color.web("#0000FF");// blue as a hex web value, implicit alpha
  75  * Color c = Color.web("#00F");// blue as a short hex web value, implicit alpha
  76  * Color c = Color.web("0000FF",1.0);// blue as a hex web value, explicit alpha
  77  * Color c = Color.web("0000FF");// blue as a hex web value, implicit alpha
  78  * Color c = Color.web("00F");// blue as a short hex web value, implicit alpha
  79  * Color c = Color.web("rgba(0,0,255,1.0)");// blue as an rgb web value, explicit alpha
  80  * Color c = Color.web("rgb(0,0,255)");// blue as an rgb web value, implicit alpha
  81  * Color c = Color.web("rgba(0,0,100%,1.0)");// blue as an rgb percent web value, explicit alpha
  82  * Color c = Color.web("rgb(0,0,100%)");// blue as an rgb percent web value, implicit alpha
  83  * Color c = Color.web("hsla(270,100%,100%,1.0)");// blue as an hsl web value, explicit alpha
  84  * Color c = Color.web("hsl(270,100%,100%)");// blue as an hsl web value, implicit alpha
  85  * }
  86  * </code></pre>
  87  *
  88  * <p>
  89  * The creation of a {@code Color} will throw {@code IllegalArgumentException} if any
  90  * of the values are out of range.
  91  * </p>
  92  *

  96  * Rectangle rec1 = new Rectangle(5, 5, 50, 40);
  97  * rec1.setFill(Color.RED);
  98  * rec1.setStroke(Color.GREEN);
  99  * rec1.setStrokeWidth(3);
 100  *
 101  * Rectangle rec2 = new Rectangle(65, 5, 50, 40);

 305      * <li>An {@code hsl(h,s,l)} or {@code hsla(h,s,l,a)} format string.

 308      * {@code 0.0} or {@code 360.0} representing red, {@code 120.0}
 309      * representing green, and {@code 240.0} representing blue.  The

 315      * brightness of the color ({@code 100.0}).

 557      * and can either be 2 digits in the range {@code 00} to {@code 0xFF} or a
 558      * single digit in the range {@code 0} to {@code F}.
 559      * <li>An {@code rgb(r,g,b)} or {@code rgba(r,g,b,a)} format string.
 560      * Each of the {@code r}, {@code g}, or {@code b} values can be an integer
 561      * from 0 to 255 or a floating point percentage value from 0.0 to 100.0
 562      * followed by the percent ({@code %}) character.

 567      * <li>An {@code hsl(h,s,l)} or {@code hsla(h,s,l,a)} format string.
 568      * The {@code h} value is a floating point number from 0.0 to 360.0
