If you use sprites with transparency in your game — and you most likely do for the UI at least — you’ll probably want to pay attention to the fully transparent pixels of your textures (or should I say “texels”). Even with an alpha of 0, a pixel still has some RGB color value associated with it. That color shouldn’t matter, right? After all if the pixel is completely transparent, who cares about it
