I'm sorry to read about your experience. I don't have your model, so I can't comment on this with my MY908. The only thing I see with my 908 is that errors, faults, or any menu options I previously clicked on, become red. I don't see any orange in my screen. You may have to e-mail Autel about the issue. Too bad the version of Android that ships with these units don't come with an Accessibility menu that can change the contrast to assist you in this regard.

I have a 906bt and under system settings you can go to "display" and adjust the
brightness and go to "accessibility" and enable triple-tap zoom which may or may not
help you but other than that I don't know
