Villagers turn into darker skin when stepped on darker bedrock. The darker bedrocks shown in picture are the ones that exploded with TNT.

The bug here is not the villager or the bedrock, it is the lighting not updating with TNT. Even though the ground should be lit from the sky now, it still shows up as Light Level 0 as it was when blocks were there. The villager's skin turning darker is a result of this. The entities change how light their skin is based on the light level they are in.
