    Description
    Color()
    Constructs a completely opaque black color object.
    Color(int color)
    Constructs a map color object from a 32-bit encoded integer.
    Color(short r, short g, short b, short a)
    Constructs a map color object from the red, green, blue and alpha components.
    Alpha component is interpreted as non-premultiplied transparency value,
    thus to make half-transparent green, use Color(0, 255, 0, 128).
