You're thinking of the difference between warm and cool colors, with blueish colors being cool and reddish colors being warm. Fact is, there can be dark reds too. You're confusing saturation with value.

@Elve, Sasuke's Susanoo has been noted to have a darker composition in comparison to Itachi's because of his hatred (at least, that's what it says on the wiki).
