AdomdClient ExecuteCellSet no fore_color

Im using AdomdClient to get some reports from cube.

I have all result values but I also would like to retreive Fore_COlor of the cell so that I added to the query command as below:

CELL PROPERTIES VALUE, FORMATTED_VALUE, FORMAT_STRING, FORE_COLOR, BACK_COLOR

Now when I iterate through cells I can see that each one has all 6 cell properties but FORE_COLOR is always 0 or null.

When I execute the same query in my management studio I can se colorful results grid.

Any hints on that? Thank You very much
