For dark mode i am just using firefox > settings > manage colors
+ forced same one font for every webpage + disabled usage of webfonts
High LCD backlighting level + dark mode with very dark red background & dark green font and you will be surprised that you can read in both outside and inside environment without changing theme. And you do not lose night vision capability. ( super secret trick from submarine )
I use same colors for KDE theme and for Firefox colors
For lowering brightness of pictures / videos i use extension Dark night mode which is little buggy with paywalls but otherwise works almost everywhere, even youtube.
KDE has Night Light mode but i need to not have red tint colors on pictures.
i do not know, but they sometimes publish altered photos with digitally added red tint in them.
( websites have to be good from accessibility standpoint to provide good experience for this. i got fed up with every webpage, font looking different. I like internet/www/hyperlink like it was meant to be consumed in early days. website is just api which provides me data and my emacs / webbrowser does styling and everything. like email or rss - decentralized, local first. because there has to be global mechanism to provide styling so there are no transitions from bright white, to dark and vice versa. and this global styling can be achieved only, if in current state of things, webpages are made in a way that screen readers and other similar kind of things have good experience too. even tho i do not have any health issue, need for accessibility features, just need for global consistent styling. )
