Hi,
I am new to Illustrator. I practice Flash more often.
In Flash, you can create symbols and apply them a color filter which includes hue, alpha, saturation parameters. So instances can vary in colors and alpha.

I hoped it would also be possible on Illustrator, but I just found this spray tool and its toll-mates affecting position, size, angle, color ...etc Good but it's only in the sets of instances that have been sprayed. I don't find it convenient for a set of isolated instances.

So is there a way to apply kind of a color filter on a given instance ?

Thank's for any help or hint,
