Thanks Alex.
I just changed Color red and Color bleu with TrachelShape color slightlyDarker.

It works perfect :)
Thanks again.

Yes please.
It would be great if 
- the modification applies uniformly to all the elements of the visualisation.
- Control the modification using a button or a key combination 
(increase/decrease)

I dont know if this possible but anyway, your solution looks fine to me :)

I should remove it.
And we should introduce this package in Pharo and I should do a pass
on the image color initialize.

Re: [Pharo-users] Roassal : Playing with the contrast

[Alexandre Bergel]

Yes, I had a look at it. Indeed, it provides a nice set of utility methods.
By the way, what the class ColorChecker does?

I will make a plugin for it in Roassal.

Re: [Pharo-users] Roassal : Playing with the contrast

[Alexandre Bergel]

Well… you can change the color of any element (even if the visualization is 
open).
Simply goes to the canvas and change the trachel shape. I can provide an 
example if you wish.

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

have a look at the package I did, it provides more named colors +
queries to select colors based on colors or intensity.
May be we should introduce the couple of methods I created into Pharo.
I did it thinking about your work with Moussa.
It could be useful for Roassal people. Now they should let me know. I
spent time harvesting all the definitions, queries, cleaning
everything. But I will not push further.
May be having some bad default colors is good for other people, but not me :).

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).
