Color Addition by Terry and Cassidy

We used 2 white lights shining on a white board, we also used 2 primary light color filters. These filters were blue and red. We  held one filter to each of the lights, by holding these 2 filters up the light we created the secondary light color magenta. This is known as color addition, it is addition because by holding only the red filter to the white light it only shines red, but when you add the blue filter the filter is only letting blue through thus creating the color magenta.
