 At +q6 thru 9 everything is fine, but at +q5 or less (for quick test renders) I get
an error message.

From the docs:

Quick Color

When developing POV-Ray scenes its often useful to do low quality test runs
that render faster. The +Q command line switch or Quality INI option can be
used to turn off some time consuming color pattern and lighting calculations
to speed things up. See "Quality Settings" for details. However all settings
of +Q5 or Quality=5 or lower turns off pigment calculations and creates gray
objects.

By adding a quick_color to a pigment you tell POV-Ray what solid color to use
for quick renders instead of a patterned pigment. For example:

  pigment {
    gradient x
    color_map{
      [0.0 color Yellow]
      [0.3 color Cyan]
      [0.6 color Magenta]
      [1.0 color Cyan]
    }
    turbulence 0.5
    lambda 1.5
    omega 0.75
    octaves 8
    quick_color Neon_Pink
  }

This tells POV-Ray to use solid Neon_Pink for test runs at quality +Q5 or
lower but to use the turbulent gradient pattern for rendering at +Q6 and higher.

Note that solid color pigments such as

  pigment {color Magenta}

automatically set the quick_color to that value.
