Ok, this adds a small glitch to my experiences:
Under a yellow bug light, part A + part B gives me a solution which is quite
green/blue - once dried on the paper, it has a more yellow cast to it, but
it seems some printing out may have already occured in the drying since this
is quite visible. As far as I can recall, this has always been the case with
my solution (and the solution of other students I've worked with). Does this
sound accurate? I haven't had any exposure fogging in high highlight areas
with it, and I've kept the solutions in brown datatainers, in a dark tool
box. once again, hmmmmm.
