What is a good way to establish visual hierarchy in a message poster made with poster colour?

Correct answer: Keep the title large and supporting text smaller

Visual hierarchy is the arrangement of elements so that viewers notice and read the most important information first. A large, clear title attracts initial attention, while smaller supporting text provides details afterward. Making every letter the same size removes priority, and making the main message smallest reverses the intended order. Randomly overlapping images and words harms readability. Thus, the larger title and smaller supporting text in option B create the clearest hierarchy.
