Document Summary
Subtractive colour mixing: mixing two or more colours together but some wavelengths of light are removes. Wavelengths of light are added ex: lights. Most evidence about colour blindness ts well. Receptors make antagonistic responses to 3 pairs of colours. The response in the cones is due to chemicals in them. Ex: if you stare at red enough, the photoreceptors of the cones becomes exhausted so when you look away for one second, it becomes green because thats all it has left of. Low or no ability to perceive one or more colours. Anomalous trichromat (most people who are colour blind) Reduced sensitivity to one of the three colours. Dichromat (most people who are colour blind) No sensitivity to one of the three. Eye has all the right cones but brain doesn"t process brain properly --> impaired processing. Perception = constructed --> we are adding our conceptions, our past experiences onto the world.
