This photograph depicts two juxtaposed black light respondent candles. One of the candles is facing a black light (left), which emits ultraviolet light. UV light contains shorter wavelengths than visible light and is invisible to the human eye. Only some objects are able to fluoresce in the visible color spectrum under UV light. The candle on the right hand side was exposed to the color spectrum. The incident colored light being shone on the candle reflects different colors from each portion of the light. The color we see in an object depends on the colors being reflected from the object, including colors of ambient light. Objects under colored light absorb specific frequencies and reflect others to the human eye. This reflected frequency is what is seen as the color.
