resistor colour codes
Designed by Martin Pot
This is designed for all the geeks and electronic hobbyists out there. It is kinda subtle, but anyone who knows electronics will immediately recognise the symbol for the resistor, as well as the colour chart! It also makes a good reference for the colour chart that you can carry around with you all the time...on the front of your shirt or on your phone cover. Also available for "black/dark backgrounds":http://www.redbubble.com/people/martybugs/works/11889554-resistor-colour-codes-on-black-and-dark-colours.
