colour.VIEWING_CONDITIONS_ZCAM

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

Define the reference ZCAM colour appearance model viewing conditions.

Provide three standard viewing conditions (Average, Dim, and Dark) with corresponding induction factors. Each condition specifies a unique surround impact factor (\(F_s\)) alongside inherited CIECAM02 parameters for maximum degree of adaptation (\(F\)), exponential non-linearity (\(c\)), and chromatic induction factor (\(N_c\)).

Notes

• The ZCAM viewing conditions inherit parameters from CIECAM02 while introducing model-specific surround impact factors: 0.69 (Average), 0.59 (Dim), and 0.525 (Dark).
