 Most `.png` images are paletted PNGs. You can edit these with any program that supports creating PNGs with palette information. These palettes should consist of exactly 4 colors. Additionally, for Pokémon images, the first color should be white, and the last black. Tools such as Paint and [GIMP](gimp) will do the right job, while other tools such as [paint.net](paintdotnet) or Photoshop might mess it up and output palettes of 255 colors even though only using 4. You may try using tools like [GraphicsGale](graphicsgale) or [IrfanView](irfanview) to fix this, or sometimes resaving the image in Paint seems to help.
 
-Some image `.png` files are greyscale. This indicates that even though these images do have proper colors in-game, they're shared with something else, and as such changing them will affect other things as well. Don't try opening the `.2bpp` files, these only contain the image data as well, not the palettes.

 It really depends on what image you're trying to change the colors of, where these colors are specified. Try looking for related files or `.pal` files.
