I took Euclidean geometry in high school, and having a book with colors like this would have made things so much easier to grasp. The color scheme is lovely too, and really makes me consider buying the poster. If you'd have told 15 year old me that I would one day really want a Euclid poster, I'd have called you insane!

I'd rather see a normal s than the long s in the text. Seems unnecessary.

Perhaps I'm alone on this, but I find all the different colors and diagrams distracting rather than helpful. It feels cluttered to me.
