Mine is this little tidbit about Khaki’s from https://www.heddels.com/2019/05/history-khaki-anything-drab/
“Tried and tested by all the major powers, khaki-dyed, lightweight cotton twills became the de facto uniform for any colonizing power. If you were going to ship your boys abroad to pillage and conquer someplace in the Southern Hemisphere, khaki was your go-to color.”
But, that’s sensible. If it’s the chemical you find in raspberry, then its natural raspberry flavor. If it’s something we invented or discovered that’s like raspberry, its artificial. Who cares if it came from a bioreactor?
While I wouldn’t recommend eating concentrated artificial flavours, touching them won’t kill you. Unless you jump into the reactor, but jumping into one would kill you no matter what the substance inside is.
