Color and human color perception
- Illuminant spectral power distribution: abbr SPD
- Spectral reflectance
- Human color vision
- Our visual system tries to “adapt” to illuminant. We may interpret the same retinal color very differently.
Retinal color space
Spectral Sensitivity Function: abbr SSF
SSF of human eye
- The human eye is a collection of light sensors called cone cells.
- There are three types of cells with different spectral sensitivity functions. (Short Medium and Long, named after the wavelengths of light they
are most sensitive to) - Human color perception is three-dimensional
