I dunno, it still looks pretty good to me. The yellow is sufficiently pale on its own, I'd almost say ship them out and let's be done with it.
It amazes me how incredibly poor SP's Quality Control is. It must be costing them a fortune to fix all these errors in every group buy. They're quick about it (a testament to their outstanding customer service) but it definitely shouldn't be this frequent. I dunno, maybe making key caps is much, much harder than I imagine.
