I'm not quite sure myself , but some refer to "blue ip" and "red ip".
I bought some IP in boxes, 100 in each, which have white/translucent paper with blue text, I guess that is what some refer to as "blue ip", I just hope that the red packages you have does not look the same on the inside..
Well, I guess I find out to the week, when I expect my blades.
No, the paper looks a lot like the box. It is not translucent at all.
