Toolkit - colors and appearance

Hi all,

I need via sdk to retrieve the top most color of a surface.

With top most I meen the color of a surface as it look into the current document.

I'm new in CREO terminology so I'll make an example

     1 - You have a PART - cube with one red surface and 5 yellow surfaces

     2 - The part belongs to an assy and the assigned color is green

     3 - The assy could belong to another assy with another colour

If I use the ProSurfaceAppearancepropsGet I retrieve RED/Yellow colour

if I use the ProSurfaceAppearancepropsGet(PART) I retrieve green

BUT I NEED TO RETRIEVE THE VISIBLE COLOR INTO THE CURRENT MODEL

Do you have any suggestion?

thanks everybody

Patrizia
