One of my favorite holiday traditions in my family is when we go to the Distillery District in Toronto (when we are visiting our family who lives there) and visit the little Christmas Market they run there. The green metal facets on the heavy brick building on the left matches (colorwise) the lit Christmas tree on the right, with the overhead sign connecting them. Warm string lights contrast against the cold gray sky. Solid, permanent architecture stands above the temporary decorations and moving crowds below. There’s also balance between big and small. The grand overhead lighting and tall buildings create scale, but the actual experience happens at ground level where individual people walk around. I think this photo demonstrates a balance between warm and cool colors, while also balancing filled and negative space.
