The idea is to come up with a simple poem where the first letter of each word represents the first letter of a color in the code. Perhaps we can demonstrate using a submission from KCBS in San Francisco. Their mnemonic reads Bowling Ball Runs Over Your Grandpa, But Victim Gets Well. Or in the resistor color code it would be Bowling for the color black. Ball is for brown.
Runs is red.
Over is the color orange. Your is obviously yellow. Grandpa would turn green from all of this. But is blue. Victim is naturally violet.
