Dealing with color casts
When shooting interiors you will sometimes find walls and ceilings with dramatically different colors. It can be a real challenge to keep those colors from "mixing" with each other and throwing a color cast over the entire image.
How do you prevent that? You use your experience and a few tools from your photographers toolbox.
In this case I was dealing with yellow, green and white (along with the furniture, window frames, sunlight coming in the window and incandesent lighting). How did I do?
