I would do this:

data = Scale_Vector(Dist(41,41), -1.06371 ,0.907327)
levels = [Min(data), Scale_Vector(findgen(17), -0.8, 0.8)]
pos = [0.1, 0.1, 0.9, 0.75]
LoadCT, 33, NColors=16, Bottom=2
TVLCT, FSC_Color('light gray', /Triple), 1
TVLCT, FSC_Color('dark gray', /Triple), 18
FSC_Display, 800, 500
FSC_Contour, data, Levels=levels, /Fill, $
C_Colors=Indgen(20)+1, Position=pos
FSC_Contour, data, Levels=levels, /Overplot, Label=2
labels = ['<-0.8', String(Scale_Vector(findgen(16), -0.8, 0.7),$
Format='(F0.1)'), '>0.8']
DCBar, NColors=18, Bottom=1, Labels=labels, charsize=0.75

This will give you a light grey color for values less
than -0.8 and a dark gray color for values greater than
0.8. Values between -0.8 and 0.8 will be in increments
of 0.1 and in normal colors.

Cheers,

David
