PPT2000: Colors Appear Wrong On Low Color Displays (198330)
The information in this article applies to:
- Microsoft PowerPoint 2000
This article was previously published under Q198330 SUMMARY
The following information describes how many colors (and what color
depths) are available in Microsoft PowerPoint and what happens when a
presentation contains more colors than can be displayed accurately given a
systems display settings.
MORE INFORMATION
Internally, PowerPoint stores color information for every object using 24-
bit (16.7 million colors) color definition. Therefore, if you insert a graphic
that contains 16.7 million colors, and you display it using a 24-bit
display driver, you see all the colors.
However, when you run a PowerPoint slide show on a system that has a 256-
color display driver, PowerPoint performs Palette Management. This means
that PowerPoint sends a palette to the display driver that contains the 256
colors that it needs the most at that one time. PowerPoint can send a
different palette to the display driver whenever it deems it necessary
(usually when changing a slide).
As long as you are running a color depth of greater than 256 colors, you
won't have to worry about running out of colors. If you are running a color
depth of 256 colors, and you have enough different graphics and gradients
on a single slide so that the slide requires more than 256 separate colors
to display, you may experience color loss, with or without an error
message.
