For pulling cable, the colors are fixed inside the jacket. I have found differences in cable manufacturers and prefer Mohawk brand cable because the colors are easier for me to see. White is white instead of clear. Blue, green, orange and brown are noticeably different. So, my take is stick to manufacturers that do a good job. If my tired old eyes can tell the difference, the employees that work with me probably won't have a problem.

My take is that I designed all to have a wide variance. IE: Red, Blue, Yellow and Black which helped lower issues. Not solve them but if you limit the use of Red to certain areas (ie: Yellow / Red on one patch panel) then it helps. Yes, I did have a team lead who was colour blind and that did help to lead me down that path. When he was on our internet facing patch panel which was Red/Yellow if he saw black he knew it was Red.

When doing Cat5 connectors, a friend couldn't tell the orange versus brown (or was it green.) He found that with a red LED flashlight he could then tell.
There are ways to work around things.
