New description:

 r.colors would benefit from a new parameter for the scaling of values:

 The parameter for scaling of values is useful when storing (big) datasets
 as scaled integer maps (factor 10 or 100) rather than floating point. This
 parameter would internally scale as requested using a standard (thematic)
 color table like e.g. Celsius, avoiding that new "celsius10" or
 "celsius100" tables must be hardcoded.
