Don't think so. There's a similar coloured dot around about the "10 o'clock" position near a white cloud. Probably a digital artifact, and/or possibly from high-energy particle. Edit - also the uniform turquoise colour is not very much like any known Jupiter moons. Io is sulphurous and most others are shades of grey. Titan around Saturn is one of the rare moons with a thick and colourful atmosphere.
