Yup, my mistake. The brown would have been my tolerance. An 542 as an E192 standard value makes sense. I guess the band spacing is what makes this all a "mess", it is not consistent with "standards" for band spacingIf you are going to start reading from the green end, then the green isn't the tolerance band. And starting from the green end, one would read 541, and that is not a standard value (542 is a standard).
