As I have gotten older and the world has become dimmer to my poor overworked eyes, I have found that balancing brightness has become harder. Comfortable screen brightness is leaving a lot of fonts difficult to read comfortably unless I make the font size huge. Specifically the Cool Temperatures are causing me some difficulty, especially if I want to make the windows more transparent.
This is a long way to stating that I would like the ability to change font colors in chat or at least have a high visibility option.
