Someone recently had me take this test to determine how colorblind I was. I failed each time and I won't post my score because its embarrassing to me. You can post your scores down below. Remember the lower score you get (1-2000) the better. Lower as in in the range of 1-20 is excellent vision.http://www.xrite.com/custom_page.aspx?PageID=77If your as colorblind as me, This is extremely hard. took me at least 45 mins to think I was doing good and ending up getting a worse score each time.
