I defined two primary personas: the Unaware, and the Informed but Idle. Analysing related sites revealed a potential gap: calm authority. A trusted friend who also happens to be a doctor. I avoided a pink-dominant palette (which can tip into the language of fighting disease rather than preventing it), building instead around natural imagery, warm cream surfaces, optimistic 'sky blue's, their lime accent, and editorial serif type with a humanist rounded sans-serif. The goal was to modernise/lighten the existing campaign's strengths rather than totally disconnect from them.
