Why this code compiles without Dtor, but not when I have one?

Reading compiler errors is a good idea:
(18-25):Error: function c739.Color.opAssign (Color p) is not
callable using argument types (Color) const
Because you use didn't supply opAssign, default one is generated.
It calls postblit and destructor for temporary. Once you define
any of them, default opAssign cannot be const and because you
assign static const structs in static constructor at lines 18-25,
compiler issues errors.
Solution is to move initialization of static fields to compile
time and use static struct initialization. In any case you know
values of Black, Green, etc. so why would one initialize them at
runtime? You can also turn them into enums.
