yes, it wasn't the main idea

Yes, that why I think it must be a different color than the one for selection 
(and also more fade, the aim is not to hide) and an optionnal mode

I don't understand. You mean if the green leads to an unclear image ? That's 
why I though about configure color by layer but as you said before it's quite 
unrealistic.

I'll think about it a little more. I should try some mockup to see what it 
could (should) looks like.
