Hi again!!
'Value tool' and 'Identity features' doesn't work as I need (01), but
finally I've found a handy and twisted way for doing it.
I needed to add a vectorial layer. Opening 'Layer Properties' dialog,
'Style' and trying to change the color of single symbol there is an option
to 'pick' a sample color from anywhere in the desktop (02).
Time to python plugin???
Thanks!!!
