The front was broken by a line of French windows, glowing now with reflected gold and wide open to the warm windy afternoon,

from F. Scott Fitzgerald – The Great Gatsby (Chapter I) on Rap Genius

Meaning

Given again the concept of old wealth, these classical French windows give the Buchanan’s house a very classical look, unlike Gatsby’s mansion which tries to innovate.

Notice the gold reference again. Gold is more associated with old money because it is considered more timeless than the dollar bills of the new money folk.
