alpha - This control the opacity of the generated color, it is a decimal between 0 to 1. it is only neccessary on rgba, hsla.
count - This control the length of the generated color. it is only neccessary when generating color that is greater than 1
Examples #
// Return a single blue color in rgba format
Options options = Options(format: Format.rgba, colorType: ColorType.blue);
var color = RandomColor.getColor(options);

/* Return a single color of type random, luminiosity random, format hex, alpha 1.0, and count is 1
i.e Options class has a default value of the following ColorType: random, Luminiosity:random, Format:hex, alpha:1.0
*/
Options options = Options();
var color = RandomColor.getColor(options);

// Return an array of ten green colors in hex format
Options options = Options(format: Format.rgba, colorType: ColorType.blue, count:10);
var color = RandomColor.getColor(options);

// Return a single color of light red in hsl format
Options options = Options(format: Format.hsl, colorType: ColorType.red, luminosity: Luminosity.light);
var color = RandomColor.getColor(options);

// Return a bright color in rgb
Options options = Options(format: Format.rgb, luminosity: Luminosity.bright);
var color = RandomColor.getColor(options);

// Return an array of 10 red and green colors in hex format
Options options = Options(format: Format.rgb, luminosity: Luminosity.bright, colorType: [ColorType.red, ColorType.green]);
var color = RandomColor.getColor(options);

// Return a dark color with a specific alpha
Options options = Options(luminosity: Luminosity.dark, alpha: 0.3);
var color = RandomColor.getColor(options);

// Return a light hsl color with a random alpha
Options options = Options(format: Format.hsla, luminosity: Luminosity.light);
var color = RandomColor.getColor(options);
