Document Summary

The rays to speak properly are not coloured. In them there is nothing else than a certain power and. Disposition to stir up a sensation of this or that colour sir isaac newton. Colour doesn"t exist the only place it exists is in your head strictly psychological. We have detectors in our body that can detect a certain kind of wavelengths and we have learned how to process this and have given it a name. An object gets its colour form the wavelength of light it reflects. The colour of an object is the wavelengths that is reflecting back to your eye to be detected by the cones. It is only when we start pulling out certain wavelengths that aren"t absorbed that we see colour everything else is absorbed. Something that is white is reflecting all the wavelengths of colour to your eye: white light = all of the visible wavelengths together.
