There is/was a site that I used to be able to select any brand of paint, and the color, and it would give me all other brands closest colors that matched it.

I cannot for the life of me find this site. I thought I got it through the advice boards here, does anyone know the site I am referring to? Sorry I don't have a more detailed description, but if you ever saw the site, you would know immediately what I'm talking about. Its hands down the best.

If anyone knows the site, or has the link. That would be awesome.
