   Relax, Brozy. Just go about your assembly and prefinish sanding. If there still appears to be some slight shadows in the color...and it's really bothering you...you can put the completed panels out in the sun for a day or two and they'll start to even out.

   The pigments in cherry are photosensitive and have what you might call a "half-life." First exposure to light causes them to darken quickly. They continue to darken at a progressively slower rate as time goes on...so the light spots may have to play catchup for awhile, but the contrast will slowly diminish over time until it is no longer noticeable. Just make sure you don't use a varnish with UV blockers and the cherry will solve its own problems.

   You should be able to sand out the dark areas pretty easily even on the thin veneer of the plywood. I've found that the dark color doesn't go down very far at all. Just be careful not to burn through.

   I have diferent experience than Justus.  I never had much luck trying to sand color out of cherry plywood..  Plus, it will all darken eventually.

   Why don't you mask off the darkened places and put the panels back out in the sun until they even up?  They'll even themselves out eventually -- there is an endpoint to the darkening process,  but it will take a long time if you don't help it out.

   I built a music sheet chest about 20 years ago out of cherry and finished it with poly with UV inhibiters.  You know that durn thing is still about the same color as when I first built it! It never dawned on me at the time.  About a year after I built it I went back and looked at the can and sure nuff!

   I have used chlorine bleach wiped onto a surface then left to dry.  You neutalize the chlorine bleach after with a wash of vinegar, to insure nothing can affect the finish.  After the vinegar is dry a light wash with water, dry, sand and finish as per normal.  If you become pushed for time you can speed up the dring of the water wash with a heat gun.
