Blue screen keying predates green and still wins in specific cases: green clothing, green props, or fine blond hair that picks up green spill. CineGlow fills any display with standard chroma blue (RGB 0,71,187), ready for OBS, CapCut, Premiere, or any keying tool.
Use any monitor, TV, or tablet as the backdrop. Keep the subject off the screen a couple of feet to dodge reflections and spill, and light the subject with a second screen running a white CineGlow preset.
Switching between green and blue is one tap on the main light — test both against your subject and keep whichever keys cleaner.
Open the blue screen →Blue is the better choice in three situations: your subject is wearing green, your subject has blond or light hair that picks up green spill, or your scene involves natural outdoor elements where green spill would contaminate foliage tones. Blue screens also tend to produce less noticeable spill on skin, at the cost of slightly noisier keys in some cameras. Test both against your actual subject and camera — the right answer is whichever keys cleaner in your software.
