For the best result when compositing, choose a genuinely neutral background that contrasts with the subject.
#60 Focus Grey is our neutral gray. It is ideal for most compositing. However; blonde hair, animal fur, or objects with gray tones can sometimes be difficult to accurately extract from a gray background because the tones are so similar. In such cases #20 Black can make detailed extractions of light tones easier. Conversely, very dark hair and clothing are more easily extracted from #66 Pure White.
