Dynamic Node Color Change [message #1703257]

Hello there,

I have a problem with my GMF Editor. I have nodes/objects that have to change their color at the moment a boolean attribute of them, called isActive, switches to false (default is of course true).
I've already found answers and solutions where I'm about to use Diagram Pins and Visual Effect mapping and the like. That I do, but this requires an OCL expression in Visual Effect Mapping which, as far as I understand Color Pins, has to return a color or color-like expression with the rgb-values in order?
I'm pretty new to GMF and even more inexperienced in ocl and as far as I was searching, the last bit of information was never revealed to me.

Help would be appreciated,
