questions on snowball shrimp

[boxedfish]

i had a few snowball shrimps and some are really translucent white in colour while a few are translucent yellowish white. I was thinking if those that are translucent yellowish white are just low-grade yellow shrimps passed off as snowball when i bought them? Or it;s normal for snowball to exhibit not totally translucent white colour?

snowball should only show translucent white , why not update a pic for us to see.

ok, i confirmed myself that they are yellow shrimps.. the yellow colours become more obvious after 1 to 2 days in my tank. When i bought them, they look white.. arhh.. selling them off, dun want them to mix with my snowballs.
