[GRASS-dev] [GRASS GIS] #3313: "None" for no color in the color rules syntax

#3313: "None" for no color in the color rules syntax
-----------------------------------------+-------------------------
Reporter: NikosA | Owner: grass-dev@…
     Type: enhancement | Status: new
Priority: normal | Milestone: 7.2.2
Component: Vector | Version: unspecified
Keywords: d.vect, rgb, none, no color | CPU: Unspecified
Platform: Unspecified |
-----------------------------------------+-------------------------
Currently the color rules syntax does not feature a "None" or "none" or,
perhaps, a "NULL" value to mean no color.

In example,

{{{
d.vect hexagons rgb=rgb_column
}}}

won't work for if the rgb_column contains "none", "None" or "NULL". A
warning reports the afore mentioned as invalid color rules.

Perhaps it would be meaningful to support them or one of them.
