Light Ground
A white, cream, or pale-gray ground left to shine through thin paint—the opposite of the warm tinted grounds of the Old Masters.
The academic nineteenth century inherited warm mid-tone grounds from Rubens and the Spanish Baroque: a painting began in the middle and moved toward the lights and the darks. The Impressionists reversed the logic. Monet, Manet, and Cézanne worked on white, cream, or pale-gray grounds that reflected light back through thin upper layers, keeping the finished painting at a permanently higher key. Manet took the idea furthest—often leaving the prepared white canvas as the highest value in the painting rather than adding lead white on top. Cézanne left patches of raw white canvas visible in his late watercolors and oils as a functional compositional element. The light ground is the material condition of Impressionist luminosity; the shift from warm tinted ground to cold white ground is the chemical pivot of nineteenth-century painting.
