I think the only reason Cure White isn’t officially a Blue is because Egret and especially Rhythm (who was part of a team that also contained blue and yellow members) exist.

But yeah, Toei has yet to deviate from the 7 main colors yet (in terms of the franchise as a whole that is, as I mentioned Moonlight is literally referred to as a silver Precure at least once in HeartCatch.

Even out of those we’ve only had 3 White Cures and 5 Green Cures while Pink (the only color that’s been consistently present in every season), Blue, Yellow, and to a lesser extent Purple and Red are much more prominent.
