Mastodon's light theme (especially with advanced interface disabled) is better than twitter's light theme, because the actual background color of the body is a light gray that's imho easier on eyes than full white but more importantly is slightly blue (#EFF3F5) so it still has personality and feels alive, while as Twitter's light theme uses almost entirely full blinding bright white and monochrome grays.
Which is weird, because Twitter's dim dark theme is very saturated and feels nice to me.
Comparison of the light bluegray background of masto light theme vs similar monochrome gray (this might not work because I still haven't fixed this tool lol) https://cervine.online/tools/palette/#EFF3F5+#EFEFEF
Twitter (blinding bright white, dead monochrome grays)
Mastodon (nice bluegray, saturated accents)
@masklayer dang remember when Twitter had some contrast
@noiob No because my memory bad and I used to use the Universal Windows App which had a dark theme instead of the desktop web version, until the uwp app became the website
@masklayer when I started using it I think it looked like the top one here. I had a mostly light blue background for the longest time which was really nice https://twirpz.files.wordpress.com/2015/06/2013-and-early-2014-twitter-profile-page-bbc-breaking.png
@masklayer hm, I might've actually been around for https://twirpz.files.wordpress.com/2015/06/2012_07_31-twitter-profile-page.png
point is Twitter used to have sensible design and wasn't always all white and big
@noiob Yeah it's weird that they got rid of basically all of the color and contrast
@masklayer and I still love Bootstrap's look (which is what Twitter was based on before the latest overhaul) https://getbootstrap.com/docs/4.5/examples/
