I finally found the solution.

Maybe I didn't state the problem very well. I have a matrix with data
points. What I wanted to do is the following: Each point should have a
certain color such that I get a smooth picture. Somehow, when I
changed the number of levels (n_levels), the color scheme just started
from the beginning.

The following pattern worked finally:

levels = 256
step = (Max(data) - Min(data)) / levels
userLevels = IndGen(levels) * step + Min(data)

contour(data,x,y,rgb_table=33,/
fill,c_value=userlevels,c_color=indgen(levels)+1)

Doing so, I have created an array of data-steps. Further, the c_color
command defines the corresponding color.
