From Day 1: the reference photo and my sketch on toned canvas
Today I underpainted with acrylic paints. I used two colors - red for warm and dark blue for cool. Basically I applied red to hotspots (the areas to be highlighted later), the sky and taxicabs. Then dark blue (it appears really dark due to the burnt sienna that I used to tone the canvas) to buildings, structures, the ground and cab windows. This is not a science project, and there is no firm rules as to what goes to where. I just kinda followed my intuition. Now it's ready for the oil treatment which will start tomorrow. Good time to take a break.
