Change the color of detail text on roSpringBoardScreen

Hi,
I have been using roSpringBoardScreen to show all the details of the episode.
I am able to change the color of all the Titles i.e. Title of episode, Title of Genre, Actors etc.
But i am unable to change the color of the text of the button, Descption, Duration, Director's Name appeared on the screen.
Which are the attributes to be set to change the color of the mentioned titles.?
Please let me know the same.

Thanks
Amit
