I agree with you about the color mapping - what a kludge!

However, you might look at Ch 4 of the tvision manual in the section entitled
'what color is your view?'. Check from there to the end of the chapter.
The last section has an example in the section 'adding new colors'.a In the
first example it shows the line
	CMyWindow = CBlueWindow + #84 ;
The #84 in this line is the _contents_ of an additional color in the palette.
Whatever #84 is, is also a mystery, but can be decoded to be bright white
on red.

The next example has the line
	CScroller = #6#7#9 ;
The #6#7#9 on this line indicates _where_ in the palette your colors _are_.

Presumably, the TProgram unit stops mapping _locations_ when the @self is
pointing to your App, at which point it starts mapping _colors_. egads.

Hope this helps...
