From PB, someone trying to start something about brown blood used in FF/fake shooting situations. Um, do you not understand how various digital cameras, and even film cameras, especially inexpensive ones, their sensors react to various lighting conditions, causing colors to be misread?
Take a red car into a parking lot at night with yellow lighting all around. You'll find that your car has turned brown. Literally, brown. You'll think you are seeing things. Nope, just what happens when colors collide.
This is the problem with public "research." Conclusions and digs based on misinformation. I see this kind of stuff here all the time.
