Any or effect to Duo tone a set of selected vectors?

Is there any way like raster effect duo tone to make vectors tow-color-tone?

For instance, Adobe Illustrator got powerful "Recolor" dialog, where such effects are do-able.

I know color styles is exists, but when there is a lot of colors and objects, it hurts!

Any workaround or trick and also any script or plugin advice will appreciated.
