Dark timber

[Luki5]

I'm putting up plywood in the bathroom. I had bought a lot of plywood from Beijer that wasn't enough, so I went to the nearest lumber yard to buy a small 2500x900 piece that was missing. I was surprised by the color difference when I put it up. I'm wondering if anyone has experienced this and if it's common with construction plywood? The Moelven sheet was bought today.

There should be a product declaration on what you bought?

I can find what I bought. Thought k20/70 was the same.
The light one is beijers RAW, https://www.beijerbygg.se/privat/sv...500x1200-5-ply-k20-70-3-0m2-65-10222500120015
And the new one is moelven vänerply 04 k20/70 c/c.

Yes, but the store where you bought it should be able to provide a product sheet detailing what type of wood is used in the sheets because they seem to be different or is it an optical illusion?

Is it possibly a wet room plywood or an uncoated plywood?

Yes, but the store where you bought it should be able to provide a product sheet about what wood species is in the boards because it looks like different ones, or is it an optical illusion?

I can't find anything about the species on RAW plywood but moelven has 98% spruce and 2% pine.
The reason for asking if it is unusual was more about whether the board has gone bad so one should put up a new one, but from what I could see at the lumberyard, the entire pile was the same color.

You should ask Beijer!
