how to remove grey stain in yellow birch?

I received some curly yellow birch from a friend recently.  It had been sitting in dry storage for several or more years.  However, after revealing the wood through jointing and planing the figured areas have grey stain in the fine grain resulting from moisture and humidity (I presume.) over the years.

Is there a way to bleach or remove the grey stain?  and or apply a dye to the wood that would mask the grey coloration and enhance the figuring?  Your advice and suggestions are appreciated.  Thank you in advance.  Tom
