This intricate coloring page features a family of five (father, mother, two sons and a daughter) sitting around a dining table. The room is dimly lit, with only a warm ray of sunshine peeking through the window that illuminates the man in the middle of the table. He is dressed in a smart black suit, holding a briefcase and with a pile of important documents in front of him. His honest gaze helps to emphasize the serious atmosphere evoked by this scene.
I suggest using a range of colors to bring this illustration to life. Use earthy tones such as creams, browns and tans for the family and the furniture in the room. The man in the suit can be dressed in more expansive colors such as navy blues and grey to emphasize his presence. The light streaming in from the window can be colored in with bold and beaming yellows and oranges. Lastly, layer with darker colors like black and charcoals to give the illustration an extra dimension of texture.
