The manual says something different/strange ... the LCD actually supports
16M colours, and so does the Visualize-EG (HP Graphitti).

... together with the fact that it just has 2MB onboard there is only
one possibility: they are referring to HP's color recovery technique.

Is there ANY way that color recovery will be supported anytime in the future?
