Safety signs

There is a convention for the colours of safety signs. It is

RED - Prohibition, danger or alarm

YELLOW or AMBER - Warnings

BLUE - Mandatory

GREEN - Emergency information, escape

Whilst signs are important, their effect is limited, and after someone has seen the same sign a few times they are unlikely to notice it. Also, too many signs can be confusing and dilute the message.
