I'm not sure where california stands on paints/VOC's and such. We've heard all kinds of stuff.
Any RM supplier up here could punch that in and mix it up. I can punch it in and get you the mix code as long as all the tinters down there are the same.
Now that I think of it, is this a real old color? The computer may list it, but as you say may not have the mix codes.
