Graphic styles that use current fill color instead of stomping them?

Question

Sorry if this is a really stupid, newbie question; I am a stupid newbie.
If I make a graphic style/appearance, it stores the colors of the fill and stroke and will then stamp that down on whatever else I apply it to (obviously). e.g. if I make a graphic style of a pale yellow fill and a bright orange dropshadow screen to make a glowing neon kind of look, and then drop that style onto a bright blue star, it will make the star pale yellow.
Is there a way to do a graphic style that _modifies_ the existing appearance instead of stomping it - e.g. dropping that graphic style on my blue star would make a pale blue fill with a bright green dropshadow screen.
e.g. A graphic style that said "make the new fill 110% value, 85% saturation, same hue as the existing fill color, add a 25 pt dropshadow that has the color of 90% value, 110% saturation, -3 hue of the existing fill color." And then that style dropped on a yellow star and a blue star would result in a glowing neon yellow star and a glowing neon blue star.
The reason I ask: I have a bunch of geometric shapes of various shades of red, orange, yellow and brown, and would like to see what they would all look like with dropshadows of dark, very desaturated complementary colors (the orange shape gets a dark blue/gray dropshadow, the yellow shape gets a dark purple/gray dropshadow, etc.). Do I have to go in and modify each appearance by hand, or is there some way I can automate that?
Thanks, and apologies if this is a really obvious question.

You won't get as much control as you describe (specific HSV values), but try putting a negative value in the Drop Shadow dialog's Darkness field.
To create a Graphic Style that can apply an Effect without disturbing the existing fill/stroke of the object(s), first group the object(s), then apply the Effect (Drop Shadow, etc.) to the Group, and then drag the Group to the Graphic Styles palette.
