not so green java moss

I just recieved some java moss from an online vendor today. Instead of the
deep-green color it is usually described as having, it was a sort of palish,
yellowish green, with some darker green patches. Is this something to be
concerned about? Will it revitalize in the aquarium after a few days, or
should I remove the stuff before it contaminates my water?
Many thanks for your help, again. :-)
