When I was a kid way back in the 1970's I am pretty sure some of the cheap very old paperback books that I learned to read from were printed in blue ink.
These days everything I find is printed in the same boring dull black ink.
What happened to the idea that Globalization was going to make everything so cheap you would have a bouquet of choices? Instead it seems like we get whatever the cheapest alternative is from everyone on the planet and zero variety at all. Even economy cars all basically look alike in a given size range as they slavishly imitate each other trying to get market share.
Bah humbug, I want blue ink and technicolor choices!
