The colors are not important aside from standardization.  If you need to
fix one end of the cable, you have to make sure it's the same as the
other end.  If you use the standard color scheme, that is not a problem.

What IS important is the pairing.  In your second example, you have
messed up the pairings.  This may work, but is not optimal.  You could
do something like this:

    white-brown, brown, white-orange, blue, white-blue, orange,
white-green, green

But there is really no reason for it.  Just stick to the standard colors
and save yourself (and anyone else who works on the cabling later) the
headaches.

Sorry, I don't follow this question.
