5.32 How many colors can NeXT machines display?

NeXT, colors

The monochrome machines can display 4 gray levels. You can use color apps on a monochrome machine, they will converted into monochrome images and dithered accordingly.

Color NeXTstations can combine 4 bits of red, green and blue primaries for a total of 4096 pure colors. The imaging functions dither the image to produce intermediate colors.

NeXTdimension can combine 8 bits of red, green and blue for 16,777,216. There are not 16 million points on the display so all can not be displayed at once. Further display technology limits the usable color space.

None of the NeXT products support color look up tables where the user can define their own color palette on a per window basis. This feature is useful for displaying images which have adaptive lookup tables, and display pure grayscale images on the color NeXTstation. On the NeXTdimension images can be converted to full 24 bit representation.
