    As far as I know, there are no colour standards for wiring in regards to RS232 implementations, only pin assignments.

    A lot of people (including myself) wire DB9 connectors to mimic a guideline colour scheme used for RS232 on RJ45 (EIA-561).

    Code (text):

    Blue    RI
    Orange  DCD
    Black   DTR
    Red     GND
    Green   RXD
    Yellow  TXD
    Brown   CTS
    White   RTS
     
    More information on this scheme can be found here: http://www.marchansen.com/tn103/

    Having said that, the YOST serial device wiring standard has been becoming more and more popular throughout the years. I would say that it is as close to being a "standard" as anything else I have seen. It's probably what I'll eventually move to in order to avoid complications in the future. More information can be found here: http://yost.com/computers/RJ45-serial/index.html

    There is a nice write-up on RS232 in the wikipedia, including a brief mention of various standards. (http://en.wikipedia.org/wiki/RS-232)

    More information on colour codes, pinouts, and standards can also be found here: http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm
