Why do Burmese monks wear maroon colored robes?

Here’s a question. What’s the easiest way to distinguish Burmese monks from their counterparts in other countries? Typically, it’s from the color of the robes. Burma is unique among Theravada Buddhist countries in one respect: the color of monk robes. While Cambodia, Thailand, Laos and Sri Lankan monks don robes dyed in bright saffron hues, Burmese monks typically dress in drab maroon or burgundy-colored robes (aside from a few outliers).
