A lightened or whitish area in a paint or varnish layer. Blanching is not a surface phenomenon like Bloom, but rather due to microscopic defects (voids, granules, etc.) that develop within a film layer as it ages. The defects can scatter light making the affected area appear lighter than the surrounding areas.
