Ffa not just for faces emotional component. 2, 3, 4, 5 and some of 8 for the 2nd midterm. Colour not a physical property psychophysical: most light is reflected broad spectrum of wavelengths o. Bitmap superimposition of green, red, blue layers. Univariance different wavelength intensity combinations can elicit exactly some response from a single type of photoreceptor: cannot make colour discrimination based on wavelength (single photoreceptor) Only the response of receptor will tell us something about light we"re looking at: output of one cone is completely ambiguous. Curve, output of receptor - line of curve that passes through output line = colour of light (wavelength) same luminance ambiguous because could be blue or orange though most receptive to green. S cones short wavelengths (blue) 440 nm. M cones medium wavelengths (green) 535 nm.
