An example of health communication posters I have always found interesting are infographics. I have added two examples to show the variations an infographic can have.
What stood out for me were the harmonious flat colours and graphics. The colours had two purposes- They were used to create visual interest and also to create an image which the viewer can easily identify. Colours were also used to segregate different portions in a pie chart. In using graphics and colours together, it becomes almost like a story in visual form. For example, in the second posters, the orange van and green blocks were used to identify amount and the visuals make it easier to understand in one glance. The colours in the health posters tend to veer towards darker colours which seem more appropriate when the information is about caring for your body or going for checkups. A darker, somber colour would probably be better for older viewers. Yet perhaps putting one colour as contrast could help to create eye-catching sections for viewers to zoom in to immediately.
The information was easy to locate too. With a line separating major sections and information being spaced comfortably apart, the poster is easy to view and understand. Information is provided in bite sized pieces and is better to digest in.
