Locating paint number

[smokey]

hi,
Im new here, i've been around the forums for over a month now, but i recently registered. I have a 2002 alero 3.4L. I'm trying to locate the paint number so i can purchase paint to fix some small rust spots. I already looked on the drivers door and there was nothing that said anything about paint, any one has an idea where i can find the code, i already fixed some spots, but when i painted it the paint did not match, so can any one help me find the paint colour. thx
