Pin 1 - Black

Pin 2 - Brown

Pin 3 - Red

Pin 4 - Orange

Pin 5 - Yellow

Pin 6 - Green

Pin 7 - Blue

Pin 8 - Violet

Pin 9 - Gray

The function of each pin will depend on what signaling standard you are using. I am also unsure if these colors are ubiquitous, or if it just a standard that is typically followed.

Keep in mind this follow a very similar color-numbering system to resistors. Just remember that resistor color-numbering starts at 0, while pinouts start with 1. You will need to memorize that black and brown come first and gray comes last, the others follow the old ROYGBV of colors. Red, Orange, Yellow, Green, Blue, Violet. Indigo is usually skipped because it is too hard to make an indigo that won't be confused as either blue or purple. It's kinda like removing the letter "I" from alphanumeric tagging systems so as to not confuse it with the numeral "1." I used this to remember how to "count" with colors in college, and I use it regularly as an EE.

To find information on various pinout standards that use the DB-9 or DSUB-9 connectors you are left to your own searching via Google or wikipedia for best results.

Good luck!
