Hi Jesse,

Thanks for writing in with your idea! We are always working to add features that improve our site, and we love getting input from our community.

I've passed your feedback along to the appropriate team and it will be part of our conversation as we plan the future of Khan Academy.

Additionally, I’d like to recommend you check out some apps that add this kind of functionality. F.lux, for example, is specifically designed to make the colors on your computer's display adapt to the time of day.

Some more options are available here:

• Redshift - Windows, Linux, BSD
• Lightbulb - Windows
• Twilight - Android
• Iris mini - Mac, Windox, Linux
• G.lux - Mac, Windows, Linux, Chrome, OS, Chrome

Thanks again for your interest in improving Khan Academy! :)

All the best,

Many computers have a night shift option, but a night mode would be awesome. I also just like a black background.

Yes, please support a dark mode. Or, even better please support multiple themes, such at a black/dark background, a high contrast theme, and a colorblind theme.

The white background and blue buttons are hard on the eyes and bad for human health.

Love everything Khan Academy is doing!

I use Firefox with the Dark Reader extension and it causes issues thanks to lack of support.

Dark mode needs to be supported.

dark mode would be beneficial , the night shift in laptop or pc adds an yellow shade but the black screen i think would be more comfortable

Blue light filters are helpful for the eyes, but not the brightness. White will remain white.

We need actual dark mode.
