Is there a reason that the colour purple is associated with royalty?

To expand on other posts: the Tyrian snail (Tyre, Lebanon) was the only source of rich purple dyes (Phonetian, Royal, etc,) and thus it’s rarity and subsequently high price, made it incredibly desirable by the wealthy and noble. For a long time it was considered *so* rare, that it was illegal for anyone except the Emperor of Rome to wear purple within the empire.
