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 De : Alexandre Bergel <alexandre.bergel@me.com> à: abdelghani ALIDRA <alidrandco@yahoo.fr>; Any question about pharo is welcome <pharo-users@lists.pharo.org> Envoyé le : Mercredi 21 février 2018 2h19 Objet : Re: [Pharo-users] Roassal : Playing with the contrast 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

Hi,
I am wondering if there is a way to play with the contrast of Roassal visualisations. If so, please tell me how :)
Thank you in advance Abdelghani
