[Blaze boy]

Hi I am very new in Pokemon community and a beginner at romhacking my issue is that whenever I import my tilesets in advance map after editing in paint it changes it's colour in advance map how can I fix it I used aseprite to make tileset and used irfanview to convert it to 16bpp and used tilehelper advance 😐

You're viewing Palette 8 in AdvanceMap. If memory serves the default "red" palette for the Pokecenter is somewhere around 2 or something. I think you're just viewing it with the wrong palette after importing.
