Chiquita Banana recently got a rebranding and introduced their sticker characters. Staying true to themselves with that familiar blue and yellow color scheme, it was imperative that they build upon their brand equity rather than start from scratch. The client's goals were kind of like that dream brief you get handed that simply says: "Make bananas cool."
