OK. Still trying to solve the problem...

Is it possible to make this kind of reclassification
PROCESSING "BANDS=1"
CLASS
   EXPRESSION ([pixel] > 250)
      STYLE
         COLOR 250 [green] [blue]
      END
END?

So what I'm trying to do is reserve certain colors from image for another
purposes and thus I need to make sure that image does not contain those
colors. Above I am trying to make sure that in the image there is no pixels
that have red (band 1) values larger than 250. The expression itself works
but how to assign color without changing green and blue values of a pixel?

If this is not possible what would be another solution?
