I immediately knew from the titles that the legendaries this time around might be based around light. Stole this from a Google search:
"Light (also referred to in professional literature as radiation) is best thought of as a spectrum consisting of ultraviolet light (UV) at the short end, visible light in the center, and infrared (IR) wavelengths at the long end."
Scarlet of course is a shade of red. Even if I'm wrong it will be interesting what the concepts they'll have planned for the boxart legendaries.
