0.3.1

1.0.0

1.1.0

• Added XYZ color space support with bidirectional conversions between XYZ and RGB color spaces.

1.2.0

• Added CIELAB color space support with bidirectional conversions with the XYZ color space (and the RGB color space using XYZ as an intermediary).

1.3.0

• Added toXXXColor() conversion methods for all possible color space transitions.
• Added Color.clone() method to make a copy of a Color object.
• Added toCssString() method to RGB, Hex, and HSL colors for easier use with CSS.

2.0.0

• Color and all subclasses now implement a const constructor.
• Colors are no longer mutable, and all conversion and filter methods return new Color objects.

• Adjusted the greyscale and invert ColorFilters to use the CIELAB color space, giving better results.
• Added a lighten and darken ColorFilter.
• Added an RgbColor.name() constructor to create colors by CSS3 name.
• Added a Color.toHexColor() method for easier conversion to the HexColor class.
• Added a CssColorSpace interface for the color spaces which have representation in the CSS standard (RGB, HEX, and HSL).
