Hi, Did you try with vpoints and the where option? I mean, in one vpoints block, select the presences with where and use color and fcolor to control outline and fill, and then, with another vpoints block select the absences. Not sure if it'll work but worth a try.
I have never used the rgb column but if none doesn't work as expected according to the manual, I think it's worth a bug report with a reproducible example from NC location.
