Derain (crater)

Derain is a crater on Mercury named after 
André Derain, a French artist, painter, sculptor and co-founder of Fauvism with Henri Matisse. It has uncommonly dark material within and surrounding the crater. The material is darker than the neighboring terrain such that this crater is easily identified even in a distant global image of Mercury. The dark halo may be material with a mineralogical composition different from the majority of Mercury's visible surface. Craters with similar dark material on or near their rims were seen on the floor of the Caloris basin during "MESSENGER"’s first flyby.
The larger and older crater Ellington is to the southeast of Derain. Both Derain and Ellington lie within a much older, 730-km-diameter, unnamed crater.
