Yes I have the same request.
It seems that, to satisfy everyone and making the games accessible for more people,
We need a button to switch between two simple, clear color-schemes, right in the official interface of the games.
A "Colors" button beside of "Show Stats" button, for exemple, that would shift the display between the present Black on White and something else, like
Dark brown on Sepia
or Light grey on Slate,
hell, even White on Black
would do, as long as we have an option.
The problem is that some people has critical eye strain and white backgrounds plus phone/computer back-light = slow building of medical issues (this is not an hypothesis, but my own experience, confirmed my a few doctors I had to see).
Now that it's no longer possible to buy CoG and Hosted games for any e-ink device, this would seem something serious and pertinent to consider.
I used to play CoG for long hours almost every day, but I have never been able to finish any new game I bought even since they stopped coming to Kindle.
