I have been always talking about the blue/cyan top coating, as seen in the second picture. I think it is in the top protective layer.

For the unprocessed paper, I believe the color can be completely washed out in rinse water (as seen in the 2nd picture). For the white part of the test strip, I can wash out the blue/cyan color with rinse water and the cover won't come back.

I believe this color has nothing to do with the image forming dye....

This paper color is documented in Fuji's document, as the Raw Material Color of the paper.
