Hello,
I was hit on the freeway several years ago and have suffered brain damage from it. As a result, I have been updating everything I can to be easier on my brain. Specifically, I use the Notes app a lot but it does not allow you to change the background color. I know you can change the font color, but I need a dark background and white text otherwise I cannot understand it. The dark theme didn't switch the background color for me, and yellowish blue light free colors practically blind me.
Any suggestions or help would be greatly appreciated.
