You are correct in thinking pair 4 should be white/brown. The color codes are: blue 1 white 0 orange 2 red 5 green 3 black 10 brown 4 yellow 15 slate 5 violet 20 Add the values together to get the pair number. If there are more than 25 pair colored binders will be used. Mutiply the binder number by 25 and add to the pair number. It's really just a base 5 numbering system. This works for up to 625 pair. If I remember correctly, 1000 pair cable has a white-blue binder around the first 500 pair and a white-orange binder around pair 500-1000, but I beleve this is the only exception. Hope this helps.
