One pullet's legs looked almost white - devoid of any yellow. But if you compare them to the true white legs of a Dorking, they are not that white. More like extremely pale yellow. When I entered this same bird in a show as a Hen, no mention was made of her leg color. I'm guessing because it's normal for yellow legs to fade with age, especially hens - from laying eggs.
The other pullet had greenish - dusky yellow legs.
Over in the thread I started about leg color, someone explained the desirable color as "butter yellow." Well, my butter is pretty pale. I think what they meant was GoldenSoft Margarine Yellow? Almost a "fake" yellow color.
I really like the leg color illustration at this link for showing various shades of yellow: https://scratchcradle.wordpress.com/2012/09/02/gms10-skin-and-shank-color/
