Using the standard HTML 3.2 color palette

splash.C creates a splash window with custom, non-theme colors, and gives an example of using standard HTML 3.2 color values, as x::w::rgb values, defined in rgb.H, for convenience:

x::w::black, x::w::gray, x::w::silver, x::w::white, x::w::maroon, x::w::red, x::w::olive, x::w::yellow, x::w::green, x::w::lime, x::w::teal, x::w::aqua, x::w::navy, x::w::blue, x::w::fuchsia, and x::w::purple.
