Document Summary
October 26, 2015 iclicker: dark bars with light intensity 3 and bright bars with light intensity 9. Three primary dimensions of colour: hue- wavelength (diagram, brightness, saturation of colour: purity of the colour. The purest colour is monochromatic (one wavelength) (ex; bright blue) Desaturated colours: mixture of wavelengths (ex; light pink or grey) Bought a prism, allowed sunlight into it through a small hole and created a rainbow (red, orange, yellow, green, blue) 3 different types of cones (differed in photopigments: blue: short wavelength (cyanolabe, green: medium wavelength (chlorolabe, red: long wavelength (erythrolabe) Had three projectors (one blue, green and red) then mixing them onto one screen. This determined we had 3 types of cones. We can easily be fooled in colour mixing because we only have the three colour receptors. If you mix red and blue and green on a green. Optical light mixing: light mixing in art: pointillism (seurat)
