In "The Song of Flying Fish" by G. K. Chesterton, the author was describing a house, saying:
Father Brown looked rather earnestly at the house, which was high and narrow, and carried rows of striped sun-blinds of gay but already faded colours. The chinks or crannies that gave glimpses of the interior looked all the darker; indeed, they looked almost black in contrast with the facade thus golden in the morning light.
Does "gay" here mean "dark"? I saw this makes more sense in this context, but I found it as "colorful" in thesaurus.com: https://www.thesaurus.com/browse/gay?s=t
And what would make it "golden" in the morning light?
