Corot's palette:
https://streamlinepublishing.
The ground is composed of lead white, over which a brown translucent undercolour has been painted which can be seen through the top paint.. Corot has used cobalt blue in the sky and in the greyish mauve of the middle distance. The mid-green foreground is created from blue and yellow, made up of a transparent yellow (possibly chrome) and a fine blue (possibly Prussian blue) mixture with white, red and black in small amounts (my emphasis).
Much has been written, from Robaut onwards, on how Corot preferred to mix his greens, rather than use ready-made ones but in actual fact he used both, as is evidenced by other paintings in the collection. The very bright orange streaks in the boat and on the woman’s cap have been identified as cadmium orange, a pigment which came into use in the latter half of the 19th century. It has also been identified in Corot’s Les Evaux, near Château Thierry, dated by Robaut to 1855 to 1865 (R1292, private collection).
