When I removed all the raw processing it went back to black ink. So I guess it's blue for raw and red for filter..This really is a neat program.

... and carry that a step further, and suppose you had a REFINE filter and that made the name blue, and then you decided to Tone Sharpen, or crop the image, or add a cutout from the Image editor screen. It would combine the red color and the blue color, and you get sort of a magenta pink color.
