I also have 5 trapezoid tables that are dark brown, and one rectangular table that is a different dark brown.
Last year I decided to use contact paper to trick the eye and make consistent. The best part was how much the color I chose warmed up the room.
Golden Oak by Magic Cover. It is incredibly easy to apply (and adjust when need be) and because of the wood grain, the seams don't really show at all!
Overall they held up really well this year. I talked to my students a lot about why I covered them. I showed them pictures of the old tables and they all agreed they liked the new ones better. I had a few kids who picked, but I just patched it up when need be.
18" x 60") rather than the short version I used last year. I think this is going to make setting up my tables a lot easier, and there will be a lot less rolls to manage!
My boards were actually painted bright blue underneath. A very cheery color, but not what I was looking for in my classroom.
I was able to staple the contact paper on (it is so much faster that way) wherever there were bulletin boards.
It even worked on the metal space next to my windows!
