Yes, I've read both of those threads before posting, but was hoping that something had changed in the past year or so.
If I knew the current accent color, I might be able to locate it in the code with a hex editor and change it, but the color mentioned in that second thread (#26A9D9) is no longer the current teal color used in the app now. #26A9D9 is more of a light blue, which would probably be closer to what I'm looking for.
EDIT: I've managed to locate the color used, and it's currently #009688 (Teal A600), so I'm going to see what I can do to change that.
