This question is based on the software known as Aseprite, a sprite and pixel art creation software. This question isn't actually about how to operate this software but more-so a way of executing a desired effect.
So, I am creating a sprite and I wish to create a glow effect on a flame. I tried using the blur tool but I feel it does not give off the look of a glowing flame. What method(s) should I use to create a glow effect?
