I've been using Aseprite which I got through Steam. It has a specific tool for swapping one color out for another that's super easy to use. I could have sworn it was free but it looks like it's going for about ten US dollars now. I think Photoshop has a function that does that as well but I assume that would be much more expensive. I think Irfanview is free and technically able to do color replacements, but I haven't ever tried to use it myself for that.
It looks like you can kind of sort of do a color replace in good old Paint, but it's a little more cumbersome. If you select the old color as color 1 and the new color as color 2, you can use the eraser tool to turn color 1 into color 2. But that obviously requires you to drag the eraser all over the sprites, which I guess isn't that bad if you make the cursor super huge. Also I'm not sure I just explained that right but there's YouTube videos and stuff that can explain it.
