rainbow background colorful gradient
Prompt
Create a photorealistic abstract rainbow background made from translucent watercolor washes on textured cold-press paper, filling the entire frame edge to edge with no objects or text. Soft overlapping gradients flow diagonally: aqua and teal in the upper left, pale mint and creamy yellow near the top center, rose pink in the upper right, deep cobalt and violet through the lower left, emerald green at mid-right, and cyan fading into lavender along the bottom. Include subtle paper grain, wet-on-wet blooms, feathered pigment edges, gentle cloud-like diffusion, and a calm uplifting mood. Even soft studio lighting, low contrast, pastel-bright palette, photographed flat lay with a 50mm lens, f/5.6, crisp texture and smooth tonal transitions.
