photoreceptor responses can vary in only one dimension
different light intensities can always be discriminated
different wavelengths cause different responses in photoreceptors
individual photoreceptors have no wavelength selectivity
Question 3
Question
A metamer is..
Answer
2 separate stimulus made up of different combinations of wavelengths appearing to be identical.
When the exactly the same wavelength in 2 stimuli are perceived as different colours.
A unit of measure in colour discrimination.
The colours that make up a perceived colour after additive mixing.
