I agree, this site is an eyesore.

I use windows color filters (Grayscale inverted is my preferred, in the past I used plain inverted) for poor man's dark mode (or light mode in this case) for stuff that doesn't honor my color scheme and hurts my eyes. It also has a hotkey, so it is really handy sometimes, but you need to enable it in the settings.

Assistive technologies are great, not only because they benefit those who have no choice but to rely on them, but also they can benefit the luckier people.
