rainbow background colorful gradient
Prompt
Create a clean photorealistic abstract background made from softly diffused colored light on a smooth matte surface, with no objects or people. The composition should be full-frame and borderless, featuring a gentle diagonal rainbow gradient: vivid hot pink and magenta dominating the left side, deep violet and blue pooling along the lower left, warm coral and soft amber blending across the upper center, and mint green, turquoise, and cyan glowing toward the right and lower right. Lighting is even, hazy, and atmospheric, like out-of-focus gel lights projected through mist, with seamless transitions and a calm modern stock-background mood. Minimal texture, no hard edges, shot as a macro studio light study on a 50mm lens, f/2.8, intentionally defocused.
