Mike, thanks for the reply. Perhaps I don't fully understand how a value is assigned to a color. Forgive me, I should have said "I am perplexed" rather then "I was mislead".
Anyways, I am still perplexed. Can you give an example on how to manipulate a red or green component? Do I need to use android.graphics.Color.rgb() or Color.red(), etc., with LightingColorFilter? I can't seem to get any color other then blue, if I don't use a neg value.
