Well-named, plain gray with black wings and dark mask. Iridescent blue-purple shoulder is usually not visible. Most similar to Palm Tanager but grayer (not olive) without pale patch at base of primaries. Also could be confused with Blue-gray Tanager in poor light, but Plain-colored's dark wings are more contrasting. Sexes alike. Seen in pairs or small flocks in open woody habitats like forest edges or shrubby second growth.
