Let users control CONTRAST of themes
The inability to change the CONTRAST of the screen makes this a very negative experience. I appreciate that the white space/gray space is meant to be "light" but some people with vision challenges need to be able to see darker shading - in mail, for instance, it's like looking at a blindingly white screen with light gray text. I would like the ability to select a theme that gives more contrast -- darker text, darker gray, but keep white, white. I can't just adjust the brightness of the screen because it doesn't change the CONTRAST of the screen elements. I'm not angry, just using all caps to emphasize the issue -- it's not that I want all dark colors, its a CONTRAST issue. And, BTW, I am a UX/UI specialist... Thanks for letting me provide my experience feedback.
