Paint Problems

Hey, does anybody know where I can find out what color my car is. I drive a 1991 Camaro RS that's white. The problem is, there are three different GM White paints. I don't want to buy some white touch up paint that is the wrong color white. I'm trying to fill in a paint chip that is about the size of a quarter, so it would really show up if I get the wrong color. Thanx for your help.

I see that about 20 people have read my question, but nobody's answering. I know, it sounds like a stupid question and you guys probably don't want to waste the time. Just so I don't sound ignorant, I would like to point out that I have checked the owners manual, the lables on the drivers side door, and the a label that I found in the spare tire area. I can't seem to find the the exact color anywhere. Thanx for any help you can give.

isn't there a sticker in the door jam or inside the console that has the paint code on it?
