I'm not sure what you're talking about. PeP has already explained the colour 
index. There are no limits in VDI when it comes to colour depth, except when 
defining the "pens" used for drawing primitives. There is nothing in the API 
that keep you from using 32 bit bitmaps.

The only thing missing from the VDI when it comes to truecolour graphics is 
bitmap transformation. In 1-8 bit modes, there is the "VDI standard format" 
for bitmaps. This is well defined, and there are VDI calls to transform this 
bitmap to the current screen layout. So you don't have to know anything 
about the pixel format/layout. In truecolour modes you have to do this 
yourself.
