Calculate color coding resistor

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