Blue represents the color of melancholy, profundity, purity and childhood dreams. This blue orange starlight, the salty and humid feeling of the ocean is as conspicuous as its name, the blue sea salt aroma, the fresh feeling of water, freedom, freshness and coldness. A typical aquatic tune, like the sea saying that sea salt and lemon are mixed with water, has a slight sour taste before it passes, and then it has the salty and wet taste of sea water. It really feels like standing on the beach, the cool feeling of the waves, with a salty and wet sea breeze.
