Last year I was uploading designs with a black graphic and white text which looked good on many of the medium colors, including Heather Blue. In fact, heather blue was a best seller in some cases. Since Amazon switched from Anvil to Port & Company standard tees, heather blue being a bit deeper, black images don't show up well on those at all. One customer reviewed the image being "too dark for shirt." It's not the end of the world, but sure would be great if we could delete a color from our listing without taking down the entire listing altogether. Thank you!
