Which consequence arises when atmospheric pollution degrades pietra dura mosaics?

💡 Explanation

Efflorescence obscures original colors because deposition creates surface salt layers, altering light reflection and color perception, driven by capillary action. Therefore, original color fidelity diminishes, rather than purely adhesive failure or broad substrate erosion affecting the design's stability.
