Hi Alex and thanks for your answer,By playing with the contrast I mean to 
change (dynamically) how visible lighter colors are from darker ones. And by 
dynamically, I mean I dont want to re-build the visu.
To be more specific, I can have for a certain visu, a shape coloured with Color 
red and bordered with Color red slightlyDarker.At some point I would like to 
see the difference between these two colours and at some other point I dont. 
So for instance, I increase the contrast and I see the border of the shape them 
I decrease it then I see the shape uniformaly coloured.
So, is there a way to do so?Thanks,Abdelghani

Hi!

What do you mean with contrasts? You mean the colors?
Currently, there is no way to automatically assign colors to a visualization, 
although you can use a color palette (look at the class RTPalette).

Cheers,
Alexandre
