Dark blue lettering on a black background makes no sense, and is difficult for many people to read. It truly detracts from the visual magnificence of the game.
I raised this issue a while ago, and a patch introduced a way that was supposed to fix the problem.
Well, the fix worked partially, in that some of the Dark Blue lettering was changed to an easy to read brighter blue. But far too much of the information in the tooltips is still in the murky Dark Blue lettering that is so hard to read against the black background.
It is not a minor issue, if you play as France, and much of the information on your forces and provinces are hidden in the Dark Blue blending into the black.
I really love this game, including Athena, and including the magnificent artwork, but this is so frustrating.
