equipped with the Deepest Visible Red and Violet filters. For the best

I may include an old program I wrote that
demonstrates both Amplitude Modulation and
Frequency Modulation, including SSB or Single Sideband production.
The Wave Interference Theory is the
best theory for understanding color mixing, but is too complex for
everyday use in Photography and Art.
