Robert -

In my experience, the color bands on "modern" resistors are just for 
decoration!  The colors are NOT true, and it is particularly difficult 
to tell the difference between black, brown and red.   Even with bright, 
color accurate lighting and high magnification.  I have given up and 
just measure them with an ohmmeter.
