Best Design Option 1. Since black is the national colour of New Zealand, the New Flag should have black colour in the background, 2. If the Flag has half black background, why not adding blue stars, because it represent the natural environment; the night has blue stars and black sky. It creates natural pleasure to human visual sense. 3. There is no need for red colour in NZ flag, we're not communist state, it only create disturbance to our vision.
