Type: Adverb (Real)
Use: Controls whether and how polarization vectors are colored.
Vectors are colored by their angle with a circular color pattern
in hue. If angles are viewed as 0 (north) to 180 (south), the
value of POL3COL selects the angle assigned to pure red and
values from eps > 0 to 180 are allowed. Color increases from
green to yellow to red to magenta to blue to cyan to green.
Null value: <= 0 -> no coloring other than dark or bright lines.
