I have so much paint! How can I organize it?!

What kind of paint? If it's from house interior, I would organize it by room. The beige in my kitchen is different than that in my living room, but not obvious if you look in the can

I write what room the paint is for on the lid.

I also put a dab of the paint on the lid rather than rely on the label.

I'm all about bigger storage buckets---> smaller storage buckets organzie iwthin organize http://www.hometalk.com/diy/q-how-to-keep-my-art-studio-clean-5117702

If you only have small amount of paint in the cans, buy small clear seal tight containers and decant into these, add a label stating colour , room and brand. Then keep all together in a shallow box or on a tray. You could use small amounts that are not wanted anymore for art projects if they are acrylics.

screw tops would be best for storing paint - AND you can add a small piece of plastic wrap to ensure you have no leaks. If it's just a tiny bit, but you need to know the color for any touch ups... you could also TAKE A PHOTO of the name / brand and if it's special mix - they usually have a BAR CODE and mixing instructions on the can lid - then TOSS the rest (into the correct recycling bin!)

I just take my brush and paint a strip on the top of the can and on a side. i'm a bit leery of using older paint for touch up...what's on the wall may end up darker that what is in the can.
