Document Summary
Two or more light sources, such as blue, green, and red colored filters, when focused together it will produce additive mixtures. Their intensity distribution curves can be added together in a process called superposition. Simple additive rules for the colored filters, not in series but placed side by side- the vertical axis is the brightness (intensity) at each wavelength. The brightness of the filters at each wavelength are added together (superposition). Colored filters are sandwiched in front of a white light. The following filter is an ideal un- saturated yellowish- green. It allows 25% of white light to pass through and 25% of yellow which can be added to 50% of the green to obtain the final color to be transmitted. The following filter is an ideal filter. It allows 25% of blue light, 100% of green light, and. Each primary color represents equal amounts of the various hues that are associated with it. (ex.
