This clipping from the 1971 dealer catalog likely does much to explain where the name "Brown", seen on cartons, came from as relates to the Earthtones bakeware set. Even though this was the first year that catalogs illustrated each pattern's array of shapes this way, it's clear the capability existed to show reasonably accurate shades of color. Perhaps this set was "reimagined" before it actually came to market. Note that 8 is the same pattern number as that of the Americana bowls.
