pink and yellow, blue and white, they're all precious in my sight

I'm out-voted on hot pink blue books, but that's ok. Turns out pink blue books already exist. From Wikipedia:

Blue books typically contain several sheets of wide-ruled notebook paper and have the words "Blue Book" across the front. However, the books' covers do not necessarily have to be blue; some schools use pink, yellow, or white covered exam books.

But now I'm curious-- Why are blue books blue (usually)? Who started that? Maybe something as simple as the printer had a lot of blue paper stock.
