No, the sky is not falling. Some states have the 3mm or so orange tip, but that is it. Canada will never likely have a law like this, because in the words of the Canadian Firearms Program "what's to stop someone from painting a real gun hot pink?". They have had issues like this in the past, and their policy is to treat ALL guns as real.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
