A rainbow painted on a wall loses its color as it crosses the threshold into the exhibit; visitors following the rainbow find themselves in a space that’s reminiscent of an old sepia photograph.
The room is lighted by sodium vapor lamps that emit a single wavelength of light—perceived as a yellowish color. Flashlights let visitors bathe objects with white light, revealing a host of colors. Filters can be used to check out objects that, under yellow light, fluoresce bright red.
According to Associate Curator Richard O. Brown, “This exhibit has something for everyone, from toddlers to scientists in the field. There are many mysteries to investigate.”
