256-Color Driver Not Showing 256 Colors in Windows 3.0 (63353)
The information in this article applies to:
- Microsoft Windows 3.0
- Microsoft Windows 3.0a
This article was previously published under Q63353 SUMMARY
Some Microsoft Windows 3.0 display drivers provide a palette of 256
simultaneous colors. The Video Seven VGA and IBM 8514/A drivers included in
the Windows 3.0 package have this capability (with an appropriate amount of
RAM on the display card).
However, such a driver does not automatically allow a given Windows
application to use 256 simultaneous colors. In a 256-color Windows 3.0
display driver, there are two sets of colors available: 16 system colors
and 240 palette colors.
To use more than the 16 system colors, an application must be specifically
written to use the Windows 3.0 palette-management capability. If the
application is not written to use palette management, it shows only 16
colors. This is not a problem with the display driver.
MORE INFORMATION
Microsoft PowerPoint for Windows is an example of an application that
uses Windows 3.00 palette management to provide you with 256-simultaneous-
color capability. The Windows 3.0 Control Panel uses system colors only, so
it does not show additional colors with a 256-color display driver. This is
because there is no need to consume valuable palette color indexes simply
to provide an additional color for menu bars, for example.
