Is there a canonical reference for the different colors of LEGO bricks?

Ideally this would be a color-matching system like Pantone or RAL but if such a reference isn't available something like sRGB would be acceptable as well.
Every color used in LEGO over the years is listed on the official LEGO color chart at Peeron. It also includes CMYK, RGB and Pantone references.
