Eggshell can be a color that resembles off-white, but it is usually a term that refers to the finish or sheen of paint. Paint companies vary somewhat is their definition of eggshell, but it is a washable interior paint with medium to low gloss.
Eggshell paint works well for use in medium-traffic rooms, such as living rooms. Because it is washable, the dirt releases easily from its surface, making it possible to keep the paint looking fresh. Eggshell paint reflects light noticeably and shows some surface imperfections. It is also recommended for use in kids' rooms, mud rooms, bathrooms, kitchens, laundry rooms and living rooms.
