Crumbling plaster revealed...

I'm trying to write the sentence below. Here is what I've got so far. Are all these ways natural? Do they all convey the same meaning? (By the way, in case my sentences are confusing, I want to describe a picture like THIS.)

The wall is blue, though crumbling plaster reveals that its original color was white.

The wall is blue, though the crumbling plaster reveals that its original color was white.

The wall is blue, though pieces of crumbling plaster reveal that its original color was white.

Don't use "crumbling pieces of plaster". That suggests that the plaster is already in pieces and it's the pieces that are crumbling. I don't think that's the case. The plaster on the wall is crumbling - into pieces.
