Background: I'm building a basic web app that's targeted toward (wait for it) academics. The app is entirely text-driven, and will not involve any images. It will incorporate some databases and longer reading material, so my driving principle here is readability and simplicity. As a front-end developer, I'm a big fan of light-on-dark color schemes as I believe they're easier on the eyes but I know many people feel the opposite.
Question: is there value to incorporating a color picker or color scheme picker into my web app to allow users to change the text color and background color according to what they find most readable, or is this feature likely to go unused?
