Calculate color coding resistance

The color coding is a very useful method to read resistors, as a number will not be readable quickly, since the orientation of a resistor is not important for functionality. However, reading this code can be confusing, especially since 5% of men (the majority of techies) are color blind. Calculate the correct value of a resistor with this tool. Please note, the gold or silver ring is always the last ring, otherwise the last ring will sometimes be a bit thicker and will have a somewhat greater distance from the adjacent rings.
