Sienna Metallic

Sienna Metallic (436) is a warm, reddish-orange metallic that Rennbow identifies as something frequently confused with the later shade Kiln Red — a comparison that confirms its position in the orange-red metallic register rather than in the conventional brown or pure red families. The color takes its name from the pigment raw sienna, derived from the earth around the Tuscan city of Siena, known for its warm ochre and burnt orange tones — and the automotive color reflects this heritage with a warm, earthy orange-red character that shifts toward bronze in certain light. It appeared on the 911 for 1976 and 1977, the 911 SC in 1979, the 912 E in 1976, and briefly on the 944 in 1983. The database entry lists it with the German designation Diamantsahara under code 436. Its rarity rating of two paint cans confirms it was seldom ordered during its available years, and the color's warm, orange-inflected metallic character made it an unusual alternative to the more conventional Copper Brown Metallic and Sienna Red Metallic options of the same period.
