Method Summary
`static int`	`blend(int color1, int color2, int opacity)` This method will blend two colors with the given factor.
`static java.awt.Color`	`brighter(java.awt.Color c)` Similar to `Color.brighter()`, but with a different `FACTOR`.
`static int`	`getHue(int color)` Returns the hue value of a given color instance as int.
`static int`	`getLuminance(int color)` Returns the luminance value of a color.
`static int`	`getRGBbyHue(int color, int hue)` Returns a Color based on rgb scheme with the given hue.
`static int`	`getRGBbyLuminance(int color, int luminance)` Returns a Color based on rgb scheme with the given luminance.
`static int`	`getRGBbyLuminanceWeb(int color, int luminance)` Takes a color value, changes its luminance value and then returns the webcompliant color instance of it.
`static int`	`getRGBColor(int[] components)` returns the color value for the given color components. the indice are defined by `INDEX_ALPHA`, `INDEX_RED`, `INDEX_GREEN` and `INDEX_BLUE`.
`static int`	`getRGBColor(int r, int g, int b)` returns the color value for the given color components.
`static int`	`getRGBColor(int r, int g, int b, int alpha)` returns the color value for the given color components.
`static int[]`	`getRGBComponents(int color)` returns the itemized components of the given color. the indices of the components in the array are defined by `INDEX_ALPHA`, `INDEX_RED`, `INDEX_GREEN` and `INDEX_BLUE`.
`static int`	`HSBtoRGB(float hue, float saturation, float brightness)` Converts the components of a color, as specified by the HSB model, to an equivalent set of values for the RGB model.
`static void`	`HSBtoRGB(float hue, float saturation, float brightness, int[] rgb)`
`static int`	`HSBtoRGBOptimized(float h, float f, float saturation, float brightness)` Converts the components of a color, as specified by the HSB model, to an equivalent set of values for the RGB model.
`static int`	`HSBtoRGBWeb(float hue, float saturation, float brightness)` Converts the components of a color, as specified by the HSB model, to an equivalent set of values for the RGB model.
`static boolean`	`isLight(int color)` Returns true if the luminance value is greater then 128.
`static float[]`	`RGBtoHSB(int r, int g, int b, float[] hsbvals)` Converts the components of a color, as specified by the default RGB model, to an equivalent set of values for hue, saturation, and brightness that are the three components of the HSB model.
`static int`	`RGBtoWeb(int r, int g, int b)` Returns the web color representation of the given rgb color.
`static int`	`setHue(int color, int hue)` Sets the hue value of the given color to the specified int.
`static int`	`setLuminance(int color, int lum)` Creates a new color with the given luminance level and returns a rgb int to reflect the change.
`static java.lang.String`	`toString(int color)` Method toString returns a formatted string representing the given color index in human readable form.
