Is My Blue is a site that allows you to test your color perception for greens and blues. I did it four times over the course of a day (it takes less than a minute) and got same result every time.
These lovely illustrations shared by Present & Correct were the inspiration for me sharing my own scans of a Carl Hansen & Son catalog.
The above are all from Present & Correct's first post on it. They've now made a second post.
Gorgeous stuff.
"In 1892, Cincinnati printer John Earhart, published The Color Printer: A Treatise on the Use of Colors in Typographic Printing, in which he detailed his methods for creating hundreds of color mixtures and thousands of color combinations as well as advice for complementary colors, using harmonious colors, and printing."
The Color Printer site is a digital edition of Earhart’s work created by Nicholas Rougeux with enhanced reproductions.
