what about this one:
Bunt[i_]:=
Module[{r1=.40,r2=.8,g1=.45,g2=.75,b1=.15,b2=.65}
,Which[i<0, RGBColor[0, 0,.3] (* 0,0,.55 *)
,i>1, RGBColor[1,.4,.4] (* 1,0,0 *)
,i===Indeterminate, RGBColor[0,0,0]
,True, RGBColor[If[i<r1,0,If[i<r2,(i-r1)/(r2-r1),1]]
,.9*If[i<g1,i/g1,If[i>g2,1-(i-g2)/(1-g2),1]]
,If[i<b1,3i+1-3b1,If[i<b2,(i-b2)/(b1-b2),0]]
]
]
]; (* Bunt *)
DensityPlot[x*y, {x,-1,1},{y,-1,1}, ColorFunction->Bunt];
