The publisher list I've been using in the last few posts actually comes from EPrints.org, using information from SHERPA/RoMEO. I'll refer to the EPrints interface as EPrints/RoMEO from now on.

This wouldn't cause any confusion and I wouldn't bother to point it out, except that RoMEO actually uses a four-colour scheme (green, blue, yellow, white) which EPrints has squished into three (green, pale green, grey).

Update: see Stevan Harnad's comment on the next entry.
