discolorations
Patches of fading
Discolorations are spots or patches where something has lost or changed its original color.
Skin discolorations may result from sun damage, bruising, or medical conditions.
Surfaces show discolorations from staining, age, or chemical exposure: The old photograph had yellow discolorations around the edges.
The singular discoloration refers to a single mark or the process itself.
