Yes. Toga candida as an expression: Its the "uniform" of the candidates in senatorial elections.
Both Albus and Candidus gave praenomen:
Albin (French, Swedish, and Scandinavian), Alban (French, Spanish), Albino (Italian, Spanish, Portuguese)
Candide (as In the Voltaire's text), and Candida (male name, originally Italian, name of a saint.)
Albion is the old name for the Great Britain.
Because, Albion was the god patron of this country.
This story, giving the name Albion for Great Britain, comes from a text *De gestis Britonum, historia regum Britanniae" by Geoffrey of Monmouth;
I think the "albicans" rather means "that makes white", whitening. As "albicans" means becoming white, as opposed with "albus".
So, it's not a plenonasm, it's a white thing that makes the other things becoming white. When the disease spreads itself, as a yeast it is.
