Not so quick. We are dealing with a specific cause of color
occurring where it should not. That after a very short fix and
some exposure to room lighting.

In order to establish fixer minimums I've conducted many
paper tests. Under fixed paper after some exposure to room
light will color. I've seen grays, warm whites, sickly yellows,
and dirty mustards. I wouldn't have thought the color would
show as quickly as it did.

The color varies with paper and color depth depends upon
the degree of under fixing. What paper are you using?
I still suggest a straight forward full fixing THEN
lights on. Ten or a few more seconds? What's
the rush? Dan
