green leg crabs ? not a emerald crab

OK so me and my wife are watching OK I am feeding she is watching.
She finds 3 crabs that have green legs with some small dots of yellow.
size 3/4" max wide area coming out of shell. not a emerald crab we have 2 and I know what look like
I have never bought green legged crabs.
could they be red legged / scarlet crabs that have molted ?
I tried to get a pic but none were worth showing blurry and could not tell the color.
are there such a thing as green legged crabs and I better start watching what the sales man or woman put in the bag for me?
any in put is appreciated !

 

I saw 3 that looked similar to what I saw, I will have my wife take a look at that id page and see what she thinks.
Thanks
