I'm no expert, but could blue refer to a super bleached fabric?
Isn't a bluing agent sometimes used to whiten discoloured white
fabric?
True white, as measured by a spectrometer, is, to most of our eyes, a
touch yellow. What we expect when we think of white is biased a little
bit towards the blue.
What does this mean to us?
A blue wash acts to blunt the yellowing in fibers and make them look
more "white." It's the original reason that old ladies used blue wash
to tint their hair. Like so many things that started out as a good
idea, it's often a touch over-done.
