I'll let wemeck post the ILC cable length conversions. My copy is at work hanging off a file cabinet and I'm not going back to work until Wed. I could probably scan it after then but it's just a bunch of colors in square boxes with sizes next to them. Simple enough nothing magical about a chart.
As for where I work, all someone did was to tape some heat shrink labels to a piece of paper next to the printed lengths and mass photo copy it. Than someone else took a bunch of highlighter markers and filled in the colors. Much more simple than using a color printer and graphically printing it all out.
Our lengths/colors for the 3" heat shrink would be:'
5' = yellow
10' = blue
15 to 20' = red
25' = white
50' = yellow
75' = red
100' = blue
125' = white
150' = yellow/blue
175' = blue/red but is going all red
200' = black
Beyond that, I have color stripes in addition to the length color to designate a specific cable for a purpose such as brown for the computerized hoist data cable, silver for the Lynx system, Masking tape for 6-
channel Clear com...
etc. You name it, and it has it's own color code. Cyan for ColorRam, Orange for Chroma
Q cable, purple for other
scroller cable, etc. In addition to orange for special cable and purple for 208v cable or green for
DMX cable. Lots of colors for special purpose stuff and adaptors. So many I not only ran out of unique colors for each type of gear thus the silver and masking tape, but I have charts all over the building saying what stuff is such as yellow/green markings on L5-20 to slip plugs, or yellow heat shrink on 3pin to 5pin adaptors. Gets really confusing. Most important part is once it's coded such as all edison to slip adaptors being black heat shrink, it's easy to find similar cables of that type.
Again, go with the color code of those you rent the most from, or if you don't usually rent, I would go with the colors of the rainbow out of symplicity. That's probably what
USITT would use anyway.
Red = 5'
Orange = 10'
Yellow = 15'
Green = 25'
Blue = 50'
Purple = 75'
Black = 100'
Grey = 125'
White = 150'
Or something like that.
