A rose by any other name would still smell as sweet. I expect that most of the names suggested—Dunn, brown, tan, beige, sand, camel, blush—would work just fine in searching for items of this color. It clearly isn’t camel, and it isn’t khaki either, but the way search engines seem to work with color names is to connect them with a broader, more general term, and spit out everything of that color. If you find one that lets you use a specific color, please post about it!
