Masculine Girl, Feminine Boy: Tamara and Samuel. OK, Samuel's not that effeminate outside of his Cure form, but at the very least his theme color is pink.
Mythology Gag: Word of God says the Cure lineup's theme colors are homage to Yes! Pretty Cure 5 and Smile Pretty Cure!, with the aspect of the Cures wearing their theme colors to school borrowed from Smile in addition to being parodied in that the two who don't wear a school uniform wear their theme colors to school every day as well. Of course, the pink-themed Cure wears a standard-issue blazer with his own school uniform.
