Color class
Image pixel colors are instantiated as an int object rather than an instance of the Color class in order to reduce object allocations. Image pixels are stored in 32-bit RGBA format (8 bits per channel). Internally in dart, this will be stored in a "small integer" on 64-bit machines, or a "medium integer" on 32-bit machines. In Javascript, this will be stored in a 64-bit double.
The Color class is used as a namespace for color operations, in an attempt to create a cleaner API for color operations.
