Coloring shapes depending on associated rgb value [message #1708827]

Hi.
I have a very simple meta-model with shapes that have a reference to a color element containing 3 values: red, green and blue.
Is it possible to create a shape that gets its color based on this element?
For instance, if I create a color in the instance model and associate a shape with this color, the shape will change color to those rgb-values?

index.php/fa/23327/0/

Thanks

EDIT: Added picture of meta-model

I think you should take a look to [1].
You can create a User Color Palette in your Viewpoint Specification
Model with Computed Colors.

Then, you can reference those color from the style descriptions in your
mappings.

The red, blue, green interpreted expressions will be evaluated on the
semantic element associated to the each graphical element.
