You'll never get an ';exact'; match, but the matches you get will be close enough. The best way is to cut a piece of your wall. The best place to take a piece from is under a light switch cover or outlet cover. If you can't get a piece from one of those spots around molding and windows is a nice spot. You don't need a big piece. A chip the size of your fingernail is big enough.To get the exact color of paint, do you have to cut a piece out of your wall, or is there another way?
The truth is





1) Impossible to match from a colour chart. If you think that's the colour, when you get it mixed, it's 3 fields and a dike out.





2) Colour shops have a hand held machine that scans the colour and gives them the possible colour code to mix. Still different.





3) Then you have shade batch problems





4) If the colour has been on a while, it would have changed colour slightly from dirt and sun shine





So, in short, you won't get the exact colour unless you have the old tin.
Places that sell paint have colored pieces of paper you can take home and match to your wall. Then take the paper back to the paint store and tell them what you want.
