So how blue is it supposed to be? Is there another simple test I could
have done to reassure myself (besides burning 30gal of it and having it
work fine)?

I've seen it all over the place. From almost navy blue (at an airport
that
doesn't get much traffic, to no discernable color at all).

Ran into this at the FBO that I fly out of at PDX-TTD. Sometimes the dye is
so pale that you have to hold it right up against a white surface such as
the vertical stabilizer to confirm the blue dye.
