A rich, deep blueberry milkshake in various shades of blue, with a velvety, dark indigo swirl, topped with a thick, creamy swirl of whipped cream in a deep, frosty blue hue. As the whipped cream falls onto the drink, dramatic splashes of the milkshake burst into the air, leaving a trail of blue droplets. Frozen blueberries are dropping into the milkshake, creating a stunning, slow-motion effect as they sink into the creamy drink, causing more vibrant blue droplets to scatter. The glass is surrounded by ice cubes and scattered frozen blueberries, all in shades of blue, giving the scene a cool, refreshing vibe. The background is a bold gradient of deep navy, cobalt, and rich indigos, enhancing the overall intensity of the image. The entire scene is filled with deep, alluring blue tones, with the splashes, flying blueberries, and smooth textures creating a dynamic and indulgent atmosphere, while the blue shades evoke both richness and cool serenity
