| 
| convert -colorspace aRGB image.png image_.png

| but looking at the doc I don't find an aRGB

| Is it possible? Which value should I use?

-colorspace is used to define the meaning of the color channels of
images in-memory.

What you are wanting is to specify the color profile of saved images.

See IM Examples, Common File Formats, Color Profiles
   http://www.imagemagick.org/Usage/formats/#color_profile

our IM should have LCMS library in use, and you will need to download
icc or icm  color profiles from somewhere.

Anyone like to give suggestions of a good source of color profiles?

Abobe photoshop will also generally imbed a "InterColorProfile"
attribute in the EXIF profile to define what color profile the image is
in when no color profile is included with the image.
