Replacing a portrait backdrop with a solid color

A man with glasses and a collared shirt in front of a bookcase.
Selected beige-gray background color, sRGB C8C1B5
Selected for this fictional author-profile example: beige-gray, sRGB #C8C1B5. The swatch specifies only the new background.

Fictional personal-author portrait: he likes his expression and glasses but needs a quieter background for his portfolio biography. The chosen beige-gray is sRGB #C8C1B5. The face, natural skin color, expression, glasses, gray shirt, pose and source lighting are preserved from the exact source. Only the background and its hair/collar edge blending change; narrow edge cleanup removes old bookshelf and plant color spill, without a general beauty or color pass.
