Chroma Key
A compositing method that replaces a single background color with another image. Petro Vlahos refined blue-screen film matting in the 1950s, and broadcast chroma key reached television studios in the 1970s for weather maps and effects.
Spot it
- 01Hard cutout subject edges
- 02Blue-green edge spill
- 03Mismatched background lighting
Why it happens
The system detects every pixel near the key color and makes it transparent, revealing a second image behind the subject, while leftover key light tints the edges.

Image edit prompt“Make this image look like a 1970s broadcast chroma key composite: the subject is sharply cut out with a faint blue rim of color spill and slightly jagged edges, placed over a flat, brighter background that does not quite match the lighting, with soft analog video color and scanlines. Keep the original subject and composition.”
