/**
 * The Color class is used to encapsulate colors in the default sRGB color space.
 * Every color has an implicit alpha value of 1.0 or an explicit one provided
 * in the constructor. The alpha value defines the transparency of a color
 * and can be  represented by a double value in the range 0.0-1.0 or 0-255.
 * An alpha value of 1.0 or 255 means that the color is completely opaque
 * and an alpha value of 0 or 0.0 means that the color is completely transparent.
 * When constructing a {@code Color} with an explicit alpha or getting
 * the color/alpha components of a Color,
 * the color components are never premultiplied by the alpha component.
 *
 *
 * <p>{@code Color}s can be created with the constructor or with one of several
 * utility methods.  The following lines of code all create the same
 * blue color:</p>
 *
 * <pre><code>
 * {@literal
 * Color c = Color.BLUE;   //use the blue constant
 * Color c = new Color(0,0,1,1.0); // standard constructor, use 0->1.0 values, explicit alpha of 1.0
 *
 * Color c = Color.color(0,0,1.0); //use 0->1.0 values. implicit alpha of 1.0
 * Color c = Color.color(0,0,1.0,1.0); //use 0->1.0 values, explicit alpha of 1.0
 *
 * Color c = Color.rgb(0,0,255); //use 0->255 integers, implicit alpha of 1.0
 * Color c = Color.rgb(0,0,255,1.0); //use 0->255 integers, explicit alpha of 1.0
 *
 * Color c = Color.hsb(270,1.0,1.0); //hue = 270, saturation & value = 1.0. inplicit alpha of 1.0
 * Color c = Color.hsb(270,1.0,1.0,1.0); //hue = 270, saturation & value = 1.0, explicit alpha of 1.0
 *
 * Color c = Color.web("0x0000FF",1.0);// blue as a hex web value, explicit alpha
 * Color c = Color.web("0x0000FF");// blue as a hex web value, implicit alpha
 * Color c = Color.web("0x00F");// blue as a short hex web value, implicit alpha
 * Color c = Color.web("#0000FF",1.0);// blue as a hex web value, explicit alpha
 * Color c = Color.web("#0000FF");// blue as a hex web value, implicit alpha
 * Color c = Color.web("#00F");// blue as a short hex web value, implicit alpha
 * Color c = Color.web("0000FF",1.0);// blue as a hex web value, explicit alpha
 * Color c = Color.web("0000FF");// blue as a hex web value, implicit alpha
 * Color c = Color.web("00F");// blue as a short hex web value, implicit alpha
 * Color c = Color.web("rgba(0,0,255,1.0)");// blue as an rgb web value, explicit alpha
 * Color c = Color.web("rgb(0,0,255)");// blue as an rgb web value, implicit alpha
 * Color c = Color.web("rgba(0,0,100%,1.0)");// blue as an rgb percent web value, explicit alpha
 * Color c = Color.web("rgb(0,0,100%)");// blue as an rgb percent web value, implicit alpha
 * Color c = Color.web("hsla(270,100%,100%,1.0)");// blue as an hsl web value, explicit alpha
 * Color c = Color.web("hsl(270,100%,100%)");// blue as an hsl web value, implicit alpha
 * }
 * </code></pre>
 *
 * <p>
 * The creation of a {@code Color} will throw {@code IllegalArgumentException} if any
 * of the values are out of range.
 * </p>
 *
 * <p>
 * For example:
 * <pre>{@code
 * Rectangle rec1 = new Rectangle(5, 5, 50, 40);
 * rec1.setFill(Color.RED);
 * rec1.setStroke(Color.GREEN);
 * rec1.setStrokeWidth(3);
 *
 * Rectangle rec2 = new Rectangle(65, 5, 50, 40);
 * rec2.setFill(Color.rgb(91, 127, 255));
 * rec2.setStroke(Color.hsb(40, 0.7, 0.8));
 * rec2.setStrokeWidth(3);
 * }</pre>

     * <li>Any standard HTML color name
     * <li>An HTML long or short format hex string with an optional hex alpha
     * channel.
     * Hexadecimal values may be preceded by either {@code "0x"} or {@code "#"}
     * and can either be 2 digits in the range {@code 00} to {@code 0xFF} or a
     * single digit in the range {@code 0} to {@code F}.
     * <li>An {@code rgb(r,g,b)} or {@code rgba(r,g,b,a)} format string.
     * Each of the {@code r}, {@code g}, or {@code b} values can be an integer
     * from 0 to 255 or a floating point percentage value from 0.0 to 100.0
     * followed by the percent ({@code %}) character.
     * The alpha component, if present, is a
     * floating point value from 0.0 to 1.0.  Spaces are allowed before or
     * after the numbers and between the percentage number and its percent
     * sign ({@code %}).
     * <li>An {@code hsl(h,s,l)} or {@code hsla(h,s,l,a)} format string.
     * The {@code h} value is a floating point number from 0.0 to 360.0
     * representing the hue angle on a color wheel in degrees with
     * {@code 0.0} or {@code 360.0} representing red, {@code 120.0}
     * representing green, and {@code 240.0} representing blue.  The
     * {@code s} value is the saturation of the desired color represented
     * as a floating point percentage from gray ({@code 0.0}) to
     * the fully saturated color ({@code 100.0}) and the {@code l} value
     * is the desired lightness or brightness of the desired color represented
     * as a floating point percentage from black ({@code 0.0}) to the full
     * brightness of the color ({@code 100.0}).
     * The alpha component, if present, is a floating
     * point value from 0.0 to 1.0.  Spaces are allowed before or
     * after the numbers and between the percentage number and its percent
     * sign ({@code %}).
     * </ul>
     *
     * <p>For formats without an alpha component and for named colors, opacity
     * is set according to the {@code opacity} argument. For colors specified
     * with an alpha component, the resulting opacity is a combination of the
     * parsed alpha component and the {@code opacity} argument, so a
     * transparent color becomes more transparent by specifying opacity.</p>

     * <ul>
     * <li>Any standard HTML color name
     * <li>An HTML long or short format hex string with an optional hex alpha
     * channel.
     * Hexadecimal values may be preceded by either {@code "0x"} or {@code "#"}
     * and can either be 2 digits in the range {@code 00} to {@code 0xFF} or a
     * single digit in the range {@code 0} to {@code F}.
     * <li>An {@code rgb(r,g,b)} or {@code rgba(r,g,b,a)} format string.
     * Each of the {@code r}, {@code g}, or {@code b} values can be an integer
     * from 0 to 255 or a floating point percentage value from 0.0 to 100.0
     * followed by the percent ({@code %}) character.
     * The alpha component, if present, is a
     * floating point value from 0.0 to 1.0.  Spaces are allowed before or
     * after the numbers and between the percentage number and its percent
     * sign ({@code %}).
     * <li>An {@code hsl(h,s,l)} or {@code hsla(h,s,l,a)} format string.
     * The {@code h} value is a floating point number from 0.0 to 360.0
     * representing the hue angle on a color wheel in degrees with
     * {@code 0.0} or {@code 360.0} representing red, {@code 120.0}
     * representing green, and {@code 240.0} representing blue.  The
     * {@code s} value is the saturation of the desired color represented
     * as a floating point percentage from gray ({@code 0.0}) to
     * the fully saturated color ({@code 100.0}) and the {@code l} value
     * is the desired lightness or brightness of the desired color represented
     * as a floating point percentage from black ({@code 0.0}) to the full
     * brightness of the color ({@code 100.0}).
     * The alpha component, if present, is a floating
     * point value from 0.0 to 1.0.  Spaces are allowed before or
