Color Recovery: True-Color 8-Bit Interactive Graphics
January-February 1997 (vol. 17 no. 1)
pp. 67-77
For many years the only practical way to display high-quality true-color images was on a computer with a graphics subsystem with at least 24 color planes. However, due to the high cost of color graphics devices with 24 planes, many users chose 8, 12, or 16 plane systems. Unfortunately, using these systems with fewer color planes requires giving up some color capabilities in order to save cost. However, an innovation called "Color Recovery" provides a method for displaying millions of colors within the cost constraints of an 8 plane system. Of course, pretty pictures aren't enough: therefore, one of the primary design goals for Color Recovery was to supply the additional color capabilities without giving up interactive performance. Another goal was to be able to work with all types of applications running in a windowed environment. An implementation of Color Recovery described in this article meets these goals.
