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 * </p>
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 * Color c = Color.BLUE; //use the blue constant
58 * Color c = new Color(0,0,1,1.0); // standard constructor, use 0->1.0 values, explicit alpha of 1.0
59 *
60 * Color c = Color.color(0,0,1.0); //use 0->1.0 values. implicit alpha of 1.0
61 * Color c = Color.color(0,0,1.0,1.0); //use 0->1.0 values, explicit alpha of 1.0
62 *
63 * Color c = Color.rgb(0,0,255); //use 0->255 integers, implicit alpha of 1.0
64 * Color c = Color.rgb(0,0,255,1.0); //use 0->255 integers, explicit alpha of 1.0
65 *
66 * Color c = Color.hsb(270,1.0,1.0); //hue = 270, saturation & value = 1.0. inplicit alpha of 1.0
67 * Color c = Color.hsb(270,1.0,1.0,1.0); //hue = 270, saturation & value = 1.0, explicit alpha of 1.0
68 *
69 * Color c = Color.web("0x0000FF",1.0);// blue as a hex web value, explicit alpha
70 * Color c = Color.web("0x0000FF");// blue as a hex web value, implicit alpha
71 * Color c = Color.web("0x00F");// blue as a short hex web value, implicit alpha
72 * Color c = Color.web("#0000FF",1.0);// blue as a hex web value, explicit alpha
73 * Color c = Color.web("#0000FF");// blue as a hex web value, implicit alpha
74 * Color c = Color.web("#00F");// blue as a short hex web value, implicit alpha
75 * Color c = Color.web("0000FF",1.0);// blue as a hex web value, explicit alpha
76 * Color c = Color.web("0000FF");// blue as a hex web value, implicit alpha
77 * Color c = Color.web("00F");// blue as a short hex web value, implicit alpha
78 * Color c = Color.web("rgba(0,0,255,1.0)");// blue as an rgb web value, explicit alpha
79 * Color c = Color.web("rgb(0,0,255)");// blue as an rgb web value, implicit alpha
80 * Color c = Color.web("rgba(0,0,100%,1.0)");// blue as an rgb percent web value, explicit alpha
81 * Color c = Color.web("rgb(0,0,100%)");// blue as an rgb percent web value, implicit alpha
82 * Color c = Color.web("hsla(270,100%,100%,1.0)");// blue as an hsl web value, explicit alpha
83 * Color c = Color.web("hsl(270,100%,100%)");// blue as an hsl web value, implicit alpha
84 * </code></pre>
85 *
86 * <p>
87 * The creation of a {@code Color} will throw {@code IllegalArgumentException} if any
88 * of the values are out of range.
89 * </p>
90 *
91 * <p>
92 * For example:
93 * <pre><code>
94 * Rectangle rec1 = new Rectangle(5, 5, 50, 40);
95 * rec1.setFill(Color.RED);
96 * rec1.setStroke(Color.GREEN);
97 * rec1.setStrokeWidth(3);
98 *
99 * Rectangle rec2 = new Rectangle(65, 5, 50, 40);
100 * rec2.setFill(Color.rgb(91, 127, 255));
101 * rec2.setStroke(Color.hsb(40, 0.7, 0.8));

297 * sign ({@code %}).
298 * <li>An {@code hsl(h,s,l)} or {@code hsla(h,s,l,a)} format string.
299 * The {@code h} value is a floating point number from 0.0 to 360.0
300 * representing the hue angle on a color wheel in degrees with
301 * {@code 0.0} or {@code 360.0} representing red, {@code 120.0}

539 * Creates an RGB color specified with an HTML or CSS attribute string.
540 *
541 * <p>
542 * This method supports the following formats:
543 * <ul>
544 * <li>Any standard HTML color name
545 * <li>An HTML long or short format hex string with an optional hex alpha
546 * channel.
547 * Hexadecimal values may be preceded by either {@code "0x"} or {@code "#"}
548 * and can either be 2 digits in the range {@code 00} to {@code 0xFF} or a
549 * single digit in the range {@code 0} to {@code F}.
550 * <li>An {@code rgb(r,g,b)} or {@code rgba(r,g,b,a)} format string.
551 * Each of the {@code r}, {@code g}, or {@code b} values can be an integer
552 * from 0 to 255 or a floating point percentage value from 0.0 to 100.0
553 * followed by the percent ({@code %}) character.
554 * The alpha component, if present, is a
555 * floating point value from 0.0 to 1.0. Spaces are allowed before or
556 * after the numbers and between the percentage number and its percent
557 * sign ({@code %}).
558 * <li>An {@code hsl(h,s,l)} or {@code hsla(h,s,l,a)} format string.
559 * The {@code h} value is a floating point number from 0.0 to 360.0
560 * representing the hue angle on a color wheel in degrees with
561 * {@code 0.0} or {@code 360.0} representing red, {@code 120.0}
562 * representing green, and {@code 240.0} representing blue. The
563 * {@code s} value is the saturation of the desired color represented
564 * as a floating point percentage from gray ({@code 0.0}) to
565 * the fully saturated color ({@code 100.0}) and the {@code l} value
566 * is the desired lightness or brightness of the desired color represented
567 * as a floating point percentage from black ({@code 0.0}) to the full
568 * brightness of the color ({@code 100.0}).
569 * The alpha component, if present, is a floating
570 * point value from 0.0 to 1.0. Spaces are allowed before or
571 * after the numbers and between the percentage number and its percent
572 * sign ({@code %}).
