Accommodating Varying Color Depths
Go Up to Programming for Varying Host Environments
To account for all deployment computers not being configured with the same color availability, the safest way is to use graphics with the least possible number of colors. This is especially true for control glyphs, which should typically use 16-color graphics. For displaying pictures, either provide multiple copies of the images in different resolutions and color depths or explain in the application the minimum resolution and color requirements for the application.
