Ceilings below unexcavated tiles are rendered in blue

I have a schist room, with a chert cavern above it. In the lower room, ceiling tiles that correspond to visible chert tiles are rendered correctly (as grey stone). Ceiling tiles below unexcavated tiles on the chert level are rendered as blue, which is somewhat of an eyesore.

Armok Vision doesn't have to cheat and reveal what the unexcavated floor tiles are, although it arguably should, since those tiles would be visible from below, but it could at least guess the composition from nearby tiles and avoid making half the ceiling bright blue.

It's a tradeoff between keeping the tiles hidden, and making them look good.

If you don't mind cheating, you can turn on showing invisible tiles, which will remove the blue.

Is that an option inside Armok Vision?

I'd like to do it only for ceilings, and for no other invisible tiles. I wouldn't even care if it lied, and just showed the invisible ceiling as whatever the adjacent, visible tile was, although that's probably more complicated to implement than just showing the ceilings.
