A Color represents a floating-point color with RGBA components. Colors can be added, subtracted, multiplied, and divided by other Colors, multiplied and divided by scalars, and support the negative operator to invert the color values.
Individual components can be read or written using the r, g, b, and a attributes, and assigned all at once by calling set(r, g, b, a=1).
By default a Color is constructed as fully-opaque black (0, 0, 0, 1).
