codes are correct. third band is your multiplier., this would make the R 56 Ohms. 0 meaning no zero's after 56. 1 meaning 1 zero which would be a brown ring how ever, the gold band is your +/- 5% accuracy of the marked reading. the brown band, because it comes after the tolerance reading normally used for quality and other markings. you make see at times were you only have 2 color bands and then a gold or Silver band, this is a fraction multiplier. gold being X 0.1 of the first 2 digits, and silver being x 0.01 etc./ you make also see another gold/silver band following it that would then indicate the tolerance. there are in some cases for more precise values 4 bands for R value and then the Multiplier. you will know when you have one of these due to the fact that gold/silver band will not appear until after 4 color bands. R,R,R,M,T instead of the R,R,M,T etc.. hope that helped some.
