Use paint designed for studio backgrounds, not standard wall paint.
A cyclorama surface has to perform on camera. That means the paint needs consistent color, controlled reflectance, and an even finish across the full background. Generic wall paint can create problems with sheen, uneven coverage, color shifts, hot spots, and inconsistent keying.
For best results, apply Pro Cyc Grey Bonding Primer before using Pro Cyc chroma key paint. The primer helps prepare the surface for better adhesion and more consistent paint coverage, especially on new or freshly finished cyc surfaces.
For chroma key work, Pro Cyc offers Virtual Green®, Dark Virtual Green®, and Virtual Blue™. The right color depends on the subject, wardrobe, lighting, camera system, and keying workflow. Green is the most common choice, but blue can be better when the subject contains green tones or when the production requires a different key color.
For white infinity backgrounds, Pro Cyc Cyclorama White™ is designed for clean, even studio use. The goal is the same in every case: a background color that reads consistently to the camera and holds up under production lighting.
