Prousalis Optics is an eyewear retail store, located in the center of Thessaloniki, Greece. After 70 years of presence, the need for a new and fresh image has emerged, in order to attract a younger audience. The icon is inspired by the owner’s personal sunglasses. It’s form was kept to a minimal aesthetic, with a coplimentary clean typography. The choice of gradients adds to the freshness of the overall appearance, whereas in the printed cards it is replaced by the use of holographic foil. This effect was inspired by the concept of the human eye’s absorption of light in all its different wavelengths and its subsequent perception of them as different colours; so does the card with the foil effect, revealing a full spectrum of colours based on your perception and how you are holding it in your hand.
