The woman in the coloring page appears to be in a very disgruntled state. Her arms are crossed, her eyebrows furrowed, and her mouth is opened wide in a scowl, reinforcing her dissatisfaction. Her posture and facial expression also declares her agitated state of mind. To add color to the page, I would choose a warm palette - perhaps some oranges, reds and yellows. One could also use light purples and blues to convey a sense of sadness and shock that she may be feeling. However, it is up to the colorer to decide the exact combination that conveys the feelings of a woman in such strong emotion.
