Hue

Hue is a puzzle game played as a side-scrolling platformer. The player controls the male character Hue who needs to find back his missing mother. She developed a ring called Annular Spectrum which allows perception and alteration of impossible colours, beyond the human spectrum. She was deceived by the traitorous professor Dr. Grey she fell in love with and has now become invisible, as a shade of such as impossible colour. It is up to Hue to restore the ring and bring her back by collecting the many scattered coloured shards.
