The bottom row of my pixel art (the letter B in the style of the BNA: Brand New Animal logo), has these weird gray pixels behind the actual art, yet I only have one layer. how do I fix this? I made the palette myself, and I know that nothing is wrong with the palette. Thank you!
EDIT: I have come to realize that the gray pixels were the transparent background. I no longer need help. Thank you to anyone who wanted to help.
