Document Summary

Light from the sun has all the possible wavelengths (white light) which contains all colours of light. Sunlight = combination of red, blue and green light = white light. Flashlight experiment: subtractive: combine red, blue and green = absorbing everything, paints and crayons. Adding pigment: mixing of a limited set of dyes, inks, paint pigments or natural colourants to create a. If it doesn"t develop in infancy, it may never develop: kitten experiment: blind. Other kittens kept in an environment with no vertical contrast. Kitts brains developed and pruned feature detectors without line patterns. Placed in room with regular lines = kittens could not see horizontal/vertical edges. Part of brain = curved, could not detect contrast: humans have similar feature detectors, contrast detectors in brain; pick up light/dark, edges, hair, depth perception, etc, face detection, symmetry; neurons specialized for identifying things making symmetry. We like strawberries that are more symmetrical than not. Brain likes and process things that are symmetrical.
