Oh Orange
There are royal houses, there have been revolutions, and there are numerable foodstuffs—from pumpkin, to carrot, to apricot, to a forward extra-strong cheddar—all of which bear the moniker orange. In fact, it is from this latter cohort that the English name for the fiery hue originates, having been named after the appearance of the ripe citrus fruit of the same name.
It’s a bold, attention-grabbing color oft used to warn of danger, to attract attention, or—as has often been the case in antique carpets—to provide just the right amount of accentuating "oomph" that sets one carpet apart from the rest.
