Didn't know that.
Though, now that I think about it, it does make sense. I went and looked at this OoTS comic and the light around the airship has some loss of color data.

After doing a bit of poking around, maybe *.PNG? It has truecolor 48-bit, though it has slightly larger file. This might be a better choice.
