Colorchallenge:tuesday orange

Hello everyone! this is my photography for the orange tuesday contest. It is a sunset on some medieval buildings (1000-1100 d.c.) of the historic center of my town Terracina in the Lazio region of Italy.
The limestone extracted from the neighboring areas my city, of white color, assumes an orange color only in some days of the sunset. So there must be certain conditions of light and visibility!

I want to highlight some typical pointed windows of the Cistercian Romanesque and Gothic period.
