If you go to my blog and scroll all the way to the bottom of the page, there is an index there called 'Index by Neat Effect'.

This was my initial stab at classifying things, and I am sure that I could go back through it again now and make some refinements, but I am happy to share it. The numbers in brackets below signify how many, out of the colours I've tested, that I've tagged with having that reaction.
I have studied more than 150 different colours, regarding how they interact with silver - reduced and unreduced, encased and unencased. These topics might be of interest to you:
Fumes brown w/silver (27)
Fumes dark w/silver (3)
Fumes yellow w/silver (15)
Turns reduced silver blue (36)
Turns reduced silver pink (4)
Turns reduced silver yellow (4)
Turns silver golden (10)
Turns unreduced silver blue (10)
Turns unreduced silver brown (3)
