Im trying to put a light kit on an outdoor craftmade ceiling fan but there is no blue or black wire to put with the black wire on light kit. I have a red, brown or purple

How about this guide? It describes how to wire your ceiling fan by wire color (http://www.ceiling-fans-n-more.com/ceiling-fan-wiring.php).

Does that help?

You will need to get a hot lead through the motor shaft. Easiest way is to run a coat hanger up, tape a blue wire on the hanger and pull back down. You will also need a neutral.
