rainbow background colorful gradient
Prompt
Create a photorealistic abstract background made from heavily defocused colored light, filling the entire frame with no objects or people. Use a smooth rainbow gradient with warm golden yellow and orange blooming from the lower left, transitioning into coral red and magenta near the lower center, teal and green across the upper middle, and cool pale cyan to deep blue on the right edge. Keep transitions soft and organic, like light passing through frosted glass or an out-of-focus lens, with subtle grain and gentle vignetting. Mood is calm, modern, vibrant, and suitable for commercial background use. Horizontal 3:2 composition, shot as macro defocused light on an 85mm lens at f/1.4, shallow depth, natural softness.
