I wonder why when swipeing between the two sides of the disc it always appears convex from the currently viewed side, but flat when viewed edge on. Anyone knows what could cause this?

#33For usable diagrams, beyond 3 sets, I always recommend upset plots, I wrote a little piece on them rather recently: https://medium.com/@harithajayasinghe/beyond-venn-diagrams-d...

#36"Lawn green" and "medium spring green" look completely identical to me. Maybe I have a really obscure kind of color blindness?

The author's mistake was this: "[my colors] are equidistant in the hue circle". The problem is that the hue circle (at least under the parameterization scheme he used) is not uniform over discrimination, i.e., the ability to discriminate two hues is not invariant under displacing them an equal amount along the circle. (I presume this is one of those situation where it's misleading to think about three primary colors on equal footing because of quirks of human vision biology.)
First, the author could have chosen 7 hues at max-saturation that were easier to discriminate than this. But more importantly, he should have used the other color axes: saturation and brightness. dark red (~maroon) and light red (~pink) are a lot easier to discriminate, even when not next to each other, than the two shades of green he used.

In all these pictures, the empty set is missing (-: . Of course you could argue that they’re also missing in Venn diagrams, but it’s common to just point on the outside.
