No, if by 'colour' we mean the optical effect of a specific light frequency (e.g. we see 650 nm wavelengths as red and 540 nm wavelengths as green).
Black is the absence of any light at all, and white is the optical effect of a roughly equal mixture of all the visible wavelengths. Hence it is impossible to make either a black or a white laser. Lasers emit only one wavelength, so they can emit any true colour but cannot emit white, which is a mixture of wavelengths, or black as that is the absence of any.
(So-called 'blacklights' actually emit ultra-violet, not black, light).
