Google for "X_COLOR_DEPTH", which is a parameter in lts.conf. That's 
about all you need to set, either globally or by station.

 From http://www.ltsp.org/documentation/lts_ig_v2.3/lts_ig_v2.3-9.html:

    This is the number of bits to use for the color depth. Possible
    values are *8*, *15*, *16*, *24* and *32*. 8 bits will give 256
    colors, 16 will give 65536 colors, 24 will give 16 million colors
    and 32 bits will give 4.2 billion colors! Not all X servers support
    all of these values. The default value for this is *16*
