It's an interesting marketing ploy but there is no such colour as woad blue, as opposed to blue dyed with woad.
The lighter blue of these bonnets is merely a result of less dyestuff being used but any shade of blue is possible from woad as it is from true Indigo.
That is essentially how Gloria explained it to me, as I had never heard of 'woad' before.
