VRayToon : how to change the color of lines ?

[theedge]

Hi,
I regularily use vraytoon to add outlines, and always did so with the default values, almost.
Today I wanted to try some renders with colored and white lines. So I simply changed the "Line Color" but that doesn't have any effect : the lines still render black. So I tried assigning a map with a color but that didn't do the trick neither.
So how to achieve that ?

ok, actually I checked again and the lines are not really black but very, very dark. So I cranked up the rgb multiplier of my vraycolor map and that did the trick.
