This animation uses 1805 colours. Ca. 1000 colours were used by under 4 pixels. Most of them approximately close. I think only 50-60 colours are really needed.
It's obvious that this image ist not made with colour limiting in mind. It looks like semi-transparent pixels on layers with transparency were added to archive the effects. They usually generate more colours. Beside being an effective technique, reducing them after animation generation is nearly impossible, only to suffice a colour count fetish.
I really like the smoke and fan animations.
Yeah, I went a bit wild with transparency effects. And this is even simplified version, original version was much crazier for smoke and staff. Still happy with that even thought it's not really classic style
