Seems a good solution by now, thanks. In particular
because the recommended RGB colors are provided by the authors
for that map.
Is there any way of displaying the annotated color table in the legend or
in the canvas for printing?

The easies way is to make a text file (classification.txt) and add the
color entries by hand. So the contents of the file will look like:
INTERPOLATION::EXACT
11,0,0,255,255,Post-flooding or irrigated croplands (or aquatic)
14,0,255,0,255,Rainfed croplands
20,255,0,255,Mosaic cropland (50-70%) / vegetation
(grassland/shrubland/forest) (20-50%)
This will set pixels 11 to blue, 14 to green and 20 to red. The format
is really basic.
pixel value, red, green, blue, alpha, label (no commas)
Then on the colormap tab, you can click the "Load color map from file"
button, second one from the top right.
Eventually it is planned that it will be able to read a variety of
different colormap formats.

I've got a landcover map in raster format (a tif file)
from GLOBOVER
(http://postel.mediasfrance.org/en/BIOGEOPHYSICAL-PRODUCTS/Land-Cover/)
The raster is opened in QGIS as "Single Band Grey"
How can I set an arbitrary color table? I can see how
to set a ramp, but this is a classified image, in which
integer values stand for different types
i,e,:
11 Post-flooding or irrigated croplands (or aquatic)
14 Rainfed croplands
20 Mosaic cropland (50-70%) / vegetation
(grassland/shrubland/forest) (20-50%)
for which different colors should be set as in "unique value"
for vector maps.
Thanks
