Material Design Pictures

Hi

in Scene Layout we can replace Pictures (Scene>>Object Picture).

In my Scene´s i replace many Material Design Icons with the same, but in a other Color.

e.g. "car.picture" in white, replace with "car.picture" in green.

The Problem:  When i would replace it live in the active scene with a button, it dont change the Object Picture, because the Filename dont change, only it´s Color.
