Color Test Pattern Generator (aka Color TPG) creates precision
alignment patterns, similar to the dot-bar generators used in color
television repair. It is intended for use in calibration and
diagnostics of early Apple color monitors and is the colorized
successor of the original Test Pattern Generator.

Color Test Pattern Generator also provides test tones just like a
signal generator.

With Color TPG, you can check: internal monitors, external monitors,
the modem port, the printer port, and all four voices of the Macintosh
sound chip.
