pgfplots: Umgang mit der colormap - Erstellen einer colormap

Wie kann ich eine colormap z.B. so einstellen, dass 0 = schwarz, 1 = blau, 2 = rot bedeutet, vorzugsweise mit Farbnamen, also etwa red, nicht rgb() usw.

Mit \pgfplotscolormapdefinemappedcolor{#1} greift man scheints auf die colormap zu, aber wie erstelle ich eine colormap zielführend?
