Chapter 9: perceiving color: colours are part of our everyday environment, we have favourite colours (blue mostly, we associate colour with emotions (purple=rage, red=embarrassment, green= envy, and blue=sad, we imbue colours with meaning (red=danger, purple= royalty, green= ecology. People identified the yellow banana as a banana. Pink= desaturated form of red: by changing the wavelength, the intensity, and the saturation, we create about a million more colors. Color and wavelength: the perception of color is related to its wavelength, the spectrum ranges from short (400nm) to long (700nm) and bands of these different wavelengths are associated with different colors. 400-450nm= violet: 450-490nm= blue, 500-575 nm green, 575-590 nm yellow, 590-620 nm= orange, 620-700 nm= red. In the case for things that are transparent (liquids, plastics etc. ) chromatic color is created by selective transmission meaning that only some wavelengths pass through the objects or substances. Summing up the connection of wavelengths and color perception: 1.
