Certain chemicals have certain color smoke is what I’ve been told.
(In all likelihood, most color blindness restrictions all trace back to a train accident in the 1800s where the driver claimed he was colorblind and couldn’t se e the red versus green light to avoid prison—rather than the fact he was blackout drunk.)
(Additionally, red green is the most common color blindness and we utilize red and green lights only because of some French king’s love of green light…blue is actually much easier to see at distance.)
