Create a dreamlike, abstract gradient background using these colors: blue (elegant & professional) . Use ultra-smooth transitions and soft directional flow to blend colors in an organic, immersive way. Incorporate natural curves, rich light diffusion, and subtle glow accents to create depth and atmosphere. Add a fine, consistent film grain texture for a soft tactile feel. Avoid harsh edges, banding, text, symbols, or recognizable objects. The background should feel modern, cinematic, and suitable for UI design or wallpaper use. Center the composition with balanced negative space and no visible borders. Ratio 1:1
