X2I'm pretty sure the standard (in the UK anyway) calls for yellow feet & legs, maybe white-ish but definitely not blue!
The USA standard is the same as UK yellow. There should not be any blue..... If a hen has been laying for a long time she will draw color out of her legs and beak...the yellow can lighten to a cream or white-ish color -- but white isn't in the standard for the legs.
