Nuage, Lilac LE 09, or Anthracite?

I saw nuage in store yesterday and it's so pretty but finances are tricky right now. I have a Lilac 09 LE and a GSH Anthracite 10 and I don't know what to do:

should I...
Let one of the Lilac or Anthra go to fund Nuage
TRY to make it possible to have all three

I have seen pictures of Lilac 09 after use and it turns a strange colour.
