white.red.green.violet.black.blue.scarlet.gold.
Advent--BLUE(BLUE-the color of the sky-helps convey that powerful message. Our Christian faith rests on the hope that Christ, who came in history assuming our flesh, will also return on the last day of time from that same blue sky he ascended long ago.)
