A good question, volume covers are visually lovely artistically speaking, and so the artists may be emphasizing the color schemes simply because. Both Mahiru and Shinoa's hair have more of a silvery tinge than what purple should have, so maybe it's considered gray since in universe that's rarer than purple so singled out since it's special. Perhaps ashen purple is the 'gray' characters refer it to as in the Seraph of the End world. Or it's simply a drawing option since lavender stands out more than an ashen color XD
