   The problem I see is the "several weeks" part of your description. I too have found that blue painters tape is meant for short term adhesion (maybe up to 1 week). The longer you leave it on, the greater chance there is for the adhesive to stick more than designed.

   Sun darkened the wood around the tape. Leave it be, and it will darken.

   If you want to hurry things, cover the dark area and leave the light part in the sun. It will even out.

   Is the light area just where the tape was, or under the cardboard corners too?

   No just under the tape, and where the tape was on the walnut parts, no change.
   I think John_C2 is onto something. The other side of the dresser had tape on the panels also, but was uneffected because it was facing a dark corner in the shop.
   Thanks for the help.

   I'm with BiotechBill, masking, striping and painter's tapes are for short term holding. The adhesives are designed to grip well but, start to degrade and do all sorts of things over time.

   Seconding John_C2's statement - this is probably not directly due to the tape but rather a difference in UV exposure. If left equally exposed to the sun it will even out in a few months.

   Agree with the additional information added. UV can quickly change wood colors. If you google sitka spruce and UV you will get a number of hits in the acoustic guitar area about this issue.
