Document Summary
Color is formed by wavelengths reflecting off an object and stimulating areas of our brain. Color is a result of our minds. Many birds, fish, reptiles and insects have excellent color vision. Among mammals color vision is limited to primates. Color vision evolved in primates to allow them to distinguish objects from there background. Some animals can see a wider range of colors than humans ie uv and infa red. Primary colors the three colors hat can be combined in various proportions to make every color in the spectrum: cannot be reduced into any other colors. There are two types of color mixing: subtractive when colored pigments selectively absorb some wavelenghs and reflect others. Primary colors red + yellow + blue. Add all get brown: additive when colored lights add their dominant colour to the mixture. How our visual system processes color by adding the effects of different wavelengths together in our nervous system.
