Everyone agrees that aerial fireworks are amazing. Here are a few beautiful photos to get you in the Independence Day spirit (here, here, here). The invention of fireworks dates back several thousand years, but the question I have been pondering is what do these amazing pyrotechnic displays look like to those who are color blind? Since 1 in 20 people are color blind, what might be done to tantalize their minds? Perhaps Matt McMahon and other visual researchers have some thoughts on this subject. Have a happy and safe weekend.
