Instead of working on my very important project, I wandered down internet lane in discovery of more information about the eyes' rods and cones. I wanted to leave a pithy comment on Andrew Finnie's post regarding this subject, but instead, lost myself in a hue test at xrite.com
I'm happy to report that from the range 0 being perfect color acuity to 99 being pretty low...I got a whopping 7! Apparently, I have a minor deficiency in the aqua range...which if funny, because aqua is my favorite color. I love what I don't know, apparently.
Take the test and feel those rods vibrate!
