Bold, saturated colour coding made navigation across the range instant and intuitive: coral pink, bright orange, electric blue, sunny yellow.
Each flavour got its own colour, and each pack featured a different animal character photographed in round glasses, looking thoughtfully intelligent and slightly ridiculous in the best possible way.
Illustration and formula graphics were layered across the packaging backgrounds: equations, molecular structures, scientific doodles, reinforcing the "smart" concept visually without ever taking it too seriously. The effect was warm, witty, and completely distinct from anything else in the category.
