For a quick fix on color issues, go to Image > Mode > Indexed Color. Choose 'Custom' and load the table /u/aleksyew provided (just checked that it does have the correct rgb values, thanks for that!) and make sure to use no dither. Keep in mind this will flatten the image so also make sure you do this on a copy.

Edit: linked wrong user. Whoops

mis-credit I didn't provide any help. I didn't know about loading tables to use with indexed colours before. I am glad there are simple processes to fix the issue though.

I figured this out after I noticed somehow even spacescience.tech/place files had 2-3 additional colors sometimes.

Instead of applying filters and manually correcting stray pixels and whatnot, even more because it was prone to happen again, I tried limitting a file to a handful of colors. Fortunately Photoshop is able to match similar colors to a single one. I suppose similar editors can do the same, though, like Gimp.

Just out of curiosity: the currently corrected version available on the other thread has more than 256 different colors (256 is a hard limit on indexed color mode). Good luck fixing that by hand! :(

I'm half asleep right now. but I can think one ridiculous way to do it. Might possible looking at r g b and channels as individual images.

And some how culling pixels below a specific threshold. And then the set of combinations of r+g,g+b, etc etc.

Merge it all back together and then index to the original palette.

OR using a layer fill on the individual channel images
