I set it to white text if value > 0.5 because black on dark blue is hard to see, but white on light blue is even worse. So we use white for dark blue and black for everything else. Not consistent design but being able to see numbers is more important and we can't do that with just black or white, and colored text would be much more inconsistent with other graphs.
