In order to catch the attention of people in the store, we are requested to make signs that are as bright and "arresting" as possible. This is the sign that I made for the section that features gluten-free and new items. It's about 40" x 30". I tried to make something as noticeable as possible and I hope it works. The store environment is packed with visual stimuli, not just signs but colorful packaging and built-up infrastructure. In order to compete with the other visual stimuli, signs have to be louder, brighter, and if possible larger than the background signage. Big letters on neon-fluorescent background! Shiny reflective metallics! Flashing lights! When these are in the environment, any additional sign has to be louder, brighter, and more eye-catching than those it is next to, leading to a "visual arms race" which can be exhausting to a more sensitive viewer.
The ultimate test of a store sign, of course, is how much of the product it sells. If gluten free and new items fly off the shelves, then my sign is a success. If they are not bought in sufficient numbers, it's back to the drawing board.
