colour.VIEWING_CONDITIONS_sCAM

colour.VIEWING_CONDITIONS_sCAM = CanonicalMapping({'Average': ..., 'Dim': ..., 'Dark': ...})

Define the reference sCAM colour appearance model viewing conditions.

Provide standardized surround conditions (Average, Dim, Dark) with their corresponding induction factors that characterize chromatic adaptation and perceptual non-linearities under different viewing environments.
