Color tables show the continuous function of the color ramp.  The color filled
contours discretize the colors, thus the disconnect.

Only if you created a color table that had discrete colors very 10 K.  Again,
the underlying color table used to sample the colors for the filled contours
usually has many more colors in it.  The color used for the fill should show
at the correct location on the color scale.  Right now, the only way
to do what you want would be to create color table with discrete colors for
each interval.  However, if you change the interval, you'd need a different
color table.

It's on our TODO list.  So many things, so little time. ;-)  I can put your
suggestion to change the color table into the hopper as well.
