I like it, I would use this as my default.

I agree it is slightly too blue for me, I think it should be more red than blue, especially since the purpose is for low-light reading.

With that said - if I toggle Dark Mode off, and then click a link, it just goes back to Dark Mode. Probably should persist.

Edit: Also, I think the Dark Mode checkbox toggle would be better placed on the profile page, with other related preferences.

Great work!
