So, in my room I have five lights; A red, orange, yellow, green, and blue light. They sit on top of a dresser and are arranged in a row, from longest wavelength to shortest. When I turn all of them on I get white light, but all shadows are broken down into each of the five colors! Mixing shadow colors makes different colors, and the closer an obect is to the lights with respect to the surface the shadows appear on, the further apart the colors are. I have noticed that certain colors only show up in certain parts of the room. For instance, I can only get a violet shadow if I am on the blue-side of the room. My question is this; would it be possible for me to get shadows in wavelengths of light outside of the visible spectrum simply by positioning the lights and object creating the shadows in the correct way?
