   Violet 7      10M         0.1%
   Grey   8                  0.05%
   White  9                 
   Gold          0.1         5%
   Silver        0.01        10%   

   Guide:
    - last band is the tolerance (+- %)
    - 2nd to last band is the multipler
    - all other proceeding bands are the decimal
      number to be multiplied by the multiplier
      
   Examples:
    [orange][violet][blue][gold][silver] 
       3       7       6    0.1   10%
    translates to a 37.6 Ohm +-10% resistor
    
    [brown][green][yellow][gold]
       1      5      10K    5%
    translates to a 150K Ohm +-5% resistor`;
