It's a colourful world in marketing, isn't it? Blue is also very common in seafood restaurants, mainly to reflect the colour of the water. For example, the low-calorie blue label low-calorie products on shelves utilise the reaction people have towards the colour by hinting at weight loss or reduced appetite. But can blue work in food beyond candy? The chances are slim. One of the biggest successes was the introduction of the blue M&M's. Plus, certain shades remind us of food gone bad. Imagine feeling full before even ordering! It's often dubbed the most 'unappetising' shade, mainly because we don't spot it much in nature's pantry (except blueberries and a few rarities). In the world of food, blue has a reputation for suppressing appetite. It represents security, trust, and dependability. In terms of using blue in branding, it's perfect for corporate brands like Unilever or Samsung. Remember how red amps up our hunger? Did you know that blue does the exact opposite?
