--- Comment #7 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2013-01-23 17:31:21 UTC --- Strange. In the GCC farm and without any customization, clang uses gray for the note. I have seen presentations where it also uses this color scheme. I don't know if they have some brackground-color detection, and it fails in your case.
