As far as I know PostScript internally works with arbitrary precise color values, regardless on how many colors you see on screen. As 24-bit color can produce more different colors than the human eye is able to differentiate, I think it does not make sense to use more colors for data repesentation of any kind, you won't see the difference. Internally you can however have as many colors as you like. CLUT-animation may by a nice toy, but it is a hack. Put in some more i860 if necessary and do REAL animation. However, if the NeXT is able to have real- time videos running from the hard-disk, it should be possible to animate what ever you want without CLUT-animation-hacks. For color calibration a CLUT is useful, and probably around, (after all NeXT is going after the DTP-market) but needs not be acessible for the general user. It suffices to have a device-driver level interface to it. --Ronald ------------------------------------------------------------------------------ "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
