All colors of different wavelength or frequency are absorbed by the black body while the white light reflects all colors.

Black and white colors are not a part of the color spectrum because black is not a color. It is just the absence of reflected light. While white color is the combination of all colors. When a white light is passed through the glass prism then it is observed that white light is spilled up into seven colors. So, it can be said that the white light absorb all colors. Thus, black and white are not real colors. But red and blue colors are the part of the color spectrum
