Hello,

yep, i think i got the idea. I've just checked the [color_me] access and this 
works. Probably the (or my) way to go is to store the color value inside the 
postgis table as extra column as suggested.

The other idea by Espen works too. But would be suited to cases with little 
variations or intermediate steps.


Thanks to everyone for the clues.
