That’s because r-munsell does not explicitly refer to r-colorspace.
Instead, r-colorspace is a propagated input of r-munsell, and propagated
inputs are something taken into account when building the profile (see
the ‘manifest’ file in there), but not other at the lower levels.

You could do, say:

  guix package -i r-munsell -p foo
  guix archive --export $(readlink foo) > t.nar
