Please add the ability to make 'black notes' darker

Please add the ability to make the color of notes that fall on 'black notes' darker than the color of white notes. I will try to explain: When I make tutorial videos (without hand playing), I choose the 5th setting of color (Divide Midi keyboard). Here I have ability to set track 1 (left hand) and track 2 (right hand) color. But then all notes from one hand will perform in the same color. It would be nice if black notes could be played in a darker color (like in Synthesia) This is much better for those who learn to play from tutorial videos. Here are the screenshots: SeeMusic:

Thank You!
