On my D-board CoCo1, after resetting to start with red, I get:

  red
  b&W with FAINT greenish tinge
  blue
  b&w with VERY FAINT goldish tinge

This is from a video add-on board, not the RF output.  The HUE control
was set to give "balanced" red & blue.  If I enable the comb filter,
ALL the colors go away, including red & blue.  I get the same display
with a video-only CoCo2 (model 26-3128) with even less secondary color
but the red & blue artifact colors remain even with the comb filter on.
