RFE: E-Ink theme about redreader HOT 6 OPEN

Do you know an Android app that simulates your display colours? I don't have an E-Ink device to test

from redreader.

Thank you. I have searched online and found that the Developer Options of Android enable one to set the screen colours as monochrome.

If you would like to add a theme using the colours stated below, prominent borders, and high contrast, I would be happy to test.

#000000
#333333
#666666
#999999
#CCCCCC
#FFFFFF

I appreciate the RedReader team's interest in accessibility. Thank you!

Thank you. I have searched online and found that the Developer Options of Android enable one to set the screen colours as monochrome.

I can activate a black and white mode on my Android 12, but it has a lot more than 8 shades of grey, and Redreader still looks good. I would need an app or option that limits the display to 8 shades of grey, and unfortunately I haven't found anything like that

It might be easiest to take a screenshot in full colour, and then use an image editor to convert it to 3-bit/1-bit monochrome to see how it looks.

Thank you, I asked on the E-Ink Reddit sub:

EDIT: A commenter on that question had some good tips:

I think apps are easier to navigate when they're mostly black and white with minimal grayscale. This helps maximize contrast. There's a VS Code theme called High Contrast for E Ink that you could reference.

Here are ideas for an e-ink friendly design system. Use solid black borders with a white background for UI elements. Invert color for UI elements you want to bring attention to, like a call-to-action button or tooltip. Check the contrast ratio for any grayscale elements. Indicate hover and active states by varying the border thickness, border style (dotted/dashed), or by using a shade of gray. Use outlined or filled icons. Prefer pagination over scrolling.
