The discussion of perceiving a dress as gold/white and blue/ black (http://www.wired.com/2015/02/science-one-agrees-color-dress/) has fascinated me. I realize the following post raises more questions than answers, but... How many times have we gotten into arguments as developers, or with clients on a particular design choice, because of a difference in perception?

This brings up an interesting topic in how to chose colors for the design of your project - none of us have any idea, if we all perceive colors so radically different.

The above image is one of my favorite "visual thought experiments". The green column is actually the same on both the left and right (#15b400)

To start framing a discussion on how to actually try and learn other people's schemas for seeing, Im using a basic image like this, and these questions are how I'd propose we start.

(my apologies that I don't have enough karma to create a poll)

What do you see in the image:

   1) Brown Stripe, left dark green
   2) Brown stripe, left bright green
   3) Purple stripe, left dark green
   4) Purple stripe, left bright green
