and the example from the manual:
https://grass.osgeo.org/grass73/manuals/i.colors.enhance.html
------
g.region raster=lsat7_2002_10 -p
i.colors.enhance blue=lsat7_2002_10 green=lsat7_2002_20 red=lsat7_2002_30
strength=95
------
it works as expected.
did you set your region to your images? could you test the manual example
with the NC sample data set?
-----
best regards
Helmut
