I want to do a series of portraits of my family and friends (for our walls) using something like the setup in pic; I want to change the background - predominantly the colour but also preserving or mimicking the variation in light to give depth. I have one person with almost white hair, a couple of dirty blondes and some almost black hair - I can use an off white/creamy coloured wall, otherwise a white sheet, or this hideous green monster! I am still deciding between all white backgrounds (my preference) or coloured (different colour for each person, everyone else's! - see palette attached :-*)
