GIFs (lesson 17) don't always show correctly as red/blue

[jeisner]

Red seems to show up okay sometimes, blue never. (On firefox.)

It's not just the GIFs that are missing blue -- it's also the model expectation in the upper right and the model probability in the tooltip that should be colored blue. They aren't either. Rounding problem? Comparison with 0 problem?
