No, because black is not an "actual" color, but the absence of colors. In other words, when you perceive a color it is because there is some electomagentic radiation that is bounced back from the object. Our retinas get exited and interptet that as a color (they interpret different colors in dependence of what frequencies are reflected). But Our brain interprets black when there is an absence of light. Thus, blacklight is an oxymoron (unless by black light you mean something entirely different, which is ultraviolet light that interacts with objects and instead of reflecting in re-radiates in a different frequency, such as the so called black light used in pubs and discos)
