Dupioni (as defined in Wikipedia) is a plain weave of silk fabric, produced by using fine thread in the warp and uneven thread reeled from two or more entangled cocoons in the weft. This gives you a very lustrous and uneven surface, which reflects the light better. This fabric goes very well with the non-uniform surface of “The Tempest”, therefore, the silk background compliments the painting. Of course the color gray is very neutral and goes very well with the blues and the cool colors, accentuated by the yellows and the reds. The selected frame brings all these into focus for the viewer.
