1. Drawing 256 colour bmps on canvas

I have  256 colour bmps which I draw on a canvas (of a drawgrid). This
works OK except when the computer is set to use 256 colours. Even though
this is the same number of colours as the bmps they look rubbish (as
though there is only 16 colours) once drawn. Does anybody know how I can
fix this?
