Here in the rainey and humid Pacific Northwest, one of the various difficulties you run into is paint storage. Metal cans tend to rust and so, long term storage of all those great colors you've accumulated gets a little dicey. Unless you use red a lot, having ferric oxide in all colors is not so great. So, to resolve this, I stopped by the local gorcery outlet on the way home and picked up 3 pallets of famous Kerr canning jars to transfer my paint into. Has the side benefit of being able to tell the color you're looking for through the glass. When you have 24+ colors hanging around, it's nice to be able to tell them apart easily.
Anyway, I started the onerous process of making labels (that includes color numbers in case I want more from the local paint guy and pouring paint into jars. Surprise, surprise. I found some very cool colors I forgot I had. Some were mislabeled on the can. Some were Brodak stuff that I had mixed other colors with or added pearl or whatever and forgot I had. So it looks like my trim color choices just increased.
Now I just have to stop at the store again to get some bigger jars. I have a lot of white, it seems.
