works fine with white media ;-)
that inspired an idea I had about the universe and primary colors.... if space is built on the canvas of time we can consider time to be black (it's arrow anyway) and the three spatial dimensions are RGB the additive primary colors. You could have an equal and opposite universe with a reverse arrow of time (white) where the spatial dimensions would correspond to CMY the subtractive primary colors. The arrow of time for all denizens in each universe would be forward for them (because they are "facing" the direction time moves, like being on a conveyor belt and facing the direction of movement) and it's the other universe that seems opposite. It explains why the universe is expanding because it only appears that way, because the other universe would appear to be contracting, so in effect the same total size is always maintained (like yin/yang). Further expanded upon this into a cyclic model of Big Bounce with expansion contraction cycles for the universe and its antiverse, divided by a barrier of light (luxon wall), because to the other universe we would seem tachyonic (going faster than light) and vice versa, with light forming the boundary between both universes (this could also have connections to the holographic principle and the boundary storing all the information contained in the bulk, where we live and for the antibulk on "the other side" too.)-- sort of like a bifurcated black hole inside an even larger universe with light keeping the two opposite universes apart and storing all their info on each side at the same time (like a double sided cosmic DVD.)
