This is always the price I pay for exporting as gifs yeah :'0

While it has limited functionality due to not being supported on my sites, I like to export things as .apngs because I can get png quality but still have animation. I do it here on FA when I wanna show multiple versions of a pic in one post.
Sites like ezgif.com have a apng maker that is a lot easier to use for the task than doing it oneself. Though it does require having a png of every frame, which could become tedious if you're doing animations all the time.
As for gifs, if you use flat colors there's a better likelihood that the export won't come out looking like it's been posterized in Photoshop. Gradients however are a no go as I've found out in the past, the effect ends up looking pretty bad.
As for your idea about exporting to a video format, that does seem to be the way that most people are going nowadays. Rare to see an actual gif file that hasn't been compressed into an mp4 or similar format when posted onto social media.

I totally feel this pain! To make my GIFs look decent, I use Krita (I don’t animate in it directly—just import PNG frames). However, the resulting file size often becomes too large for platform upload limits

Were you using on like, Adobe Flash/Animate to export animated GIFs? Although I do not know how you did your way of exporting animation GIFs, and since it has been so long from the last time I've done animated GIFs back in 2022, I had discovered how I solved the issue with the color correction, although I did things little bit differently, by drawing frames on Photoshop and turn into png file, and then import those frames of png files on Adobe Animate, and then change the Bitmap Properties of that png file by changing the Compression of Photo (JPEG) to Lossless (PNG/GIF), this fixes the color correction when exporting animated GIF files. The reason of why the exported GIF file shows the color not matching correctly is because it was set on Photo (JPEG) in the Compression of the png file's Bitmap, the same can be said for exporting into a video format.

There is an option to export with noise that makes it look less horrific :D
I saw other artists post gif on FA and video version on E6

I like the idea of colored animations, yours animations look so good and well detailed

and sent as video as to make it easy for colors to be retained sounds like a good idea,

on another note cause im curious, your animations are loops, is it possible to pay extra to add more to animation like im talking about adding like another scene where characters would climax or do something to finish up what they where doing already?

I'm interested in doing slightly longer animations but my skill level isn't there quite yet. :) I need more practice, specifically with climax scenes.

gif works really well with flat color animations, anything with shading will ruin them however ... you might be able to get some APNGs going but not all websites and browsers can handle them.
I've heard Dithering might be a quick hack to make gifs seem higher quality, but it just makes the animation noisy.
There's also the whole FA resizing/compressing gifs super hard now ... so that might not work well nowadays

I feel your pain

I found that the best way to keep colors somewhat consistent with the original while still keeping file size down was to use GIMP. Of all the programs I tried (without manually setting the colors yourself) it has the best optimization that I could find. It does take a little tinkering to get it to work, and then it takes a few minutes for it to process correctly, but it gave me results that no other program could match. Though it's been years since I last did it.
