You do not see any similarities? Purple is essentially half blue, half red so to say there's no similarity at all between purple and crimson is silly given than red IS a significant essential component of the color purple. Regardless, the concept is how they would both appear, in close proximity, together in the skyline, in less than optimal lighting, etc.Just out of curiosity...
How is Crimson too similar to Apollo's Chariot? How is Crimson too similar to bright purple???
