I am by no means an expert but when I was in Barneys BH yesterday there was a huge difference in the appearance of various yellow bags. Could be the difference between new and old patterns as yokie pointed out, but basically the "darker" yellow looks like the artist went really heavy with the black like in rvi101's second pic in post #5 above. They had a Fidji that looked like that, but they also had other yellow pieces that looked more similar to scholastican's St Louis.
