How to change block background color using block callbacks(during the simulation)

Let say I have a masked subsystem containing one input(In1) and one output(Out1).

Let say In1 is clock data(increasing during the simulation) and Out1 is In1+.

I want to change the masked subsystem background color after Out1 is greater than 10.

I want to do this by using Block properties callbacks of the masked subsystem.

Is there any way to do this?
