Historical Models — Classic CAMs & Adaptation
Foundational colour appearance and adaptation models that shaped modern colour science.
CIECAM97s Model
CIE's first comprehensive colour appearance model, establishing the framework for modern CAMs.
Open CIECAM97s- CIE standard model
- Chromatic adaptation
- Foundation for CIECAM02
Hunt Model
Robert Hunt's comprehensive colour appearance model accounting for luminance adaptation and surround effects.
Open Hunt Model- Luminance adaptation
- Surround effects
- Comprehensive appearance
Moon-Spencer Model
Early colour harmony and appearance model by Moon and Spencer for aesthetic colour relationships.
Open Moon-Spencer- Colour harmony theory
- Aesthetic relationships
- Historical significance
Naka-Rushton Model
Photoreceptor response model describing the non-linear relationship between stimulus intensity and neural response.
Open Naka-Rushton- Photoreceptor response
- Non-linear adaptation
- Neural response curve
Stevens Power Law Model
Psychophysical power law relating stimulus intensity to perceived magnitude across sensory modalities.
Open Stevens Power Law- Psychophysical law
- Brightness perception
- Power function exponent
