Currently I'm using 0.8.3 and using a ui_column visual style called gummy.fsc

I'm now playing around with fb 0.9.3.1 on another testing machine before I move to 0.9.3.1 on my daily use machine.

In 0.9.3.1 I imported the gummy.fsc but the color scheme is a little different as show below

As you can see, in 0.9.3.1, the style just a whole orange in color and totally different under 0.8.3

As I heard they are different. I don't use fcs, so I don't know but maybe you can find an updated version for your fcs or try to tweak it yourself.
