Probably not for a few reasons. The main one being I like the way they look already and the other is that it takes more time than one would think to make the change. It's not just as simple as recoloring the hair. Most of the time I have to remove everything surrounding the hair to isolate it so I can then recolor it. The same applies to just about everything else like clothes and while this is nowhere near as hard as making the actual drawing in the first place it does require quite a bit of time to do it right. That being said I did make some very minor tweaks such as adding eyeliner to Kylira and which is noticeable when she blinks in her animation.
Compare the two for some slight changes.
And while I'm not complaining about new content coming out every single week it does keep adding onto the pile of things to do. I still haven't even seen any of the content since the last 2.06 release. I have been working on the ui/map since the last release pretty much made my previous work there useless and I find the game unplayable with the stock ui/map.
@AHairyLobster Here's what I came up with for now for dealing with the change to a white text font. I don't like it better than what I had come up for the black text. Hopefully, they will switch it back over the next few updates. If anyone else wants to give it a shot. Just replace the "base color.png" file in the "ui" folder of the .jar file with this image.
