Yes agreed. I'd be more inclined to reverse the reading material of blue & red. Green is really the only remotely accurate one. My friend claims purple doesn't read is meant to reflect practicality/lack of creativity, but that applies just as much to blue. Personally I love both theory & history so I'd claim purple reads everything. Which is true of the handful of purple folks I know. We seem to be by far the rarest.
And yeah, the propaganda - don't get me started. Just seems to be ever increasing, too.
