Your beauty pass composed from several basic channels: diffuse (or some renderers call it lighting, e.g. vray ), reflection, refraction, specular. So lighting channel it is your beauty pass -(minus) reflection - refraction - specular. I assume that you are using architectural shader and don't use GI or Self Illumination. And you can find it in the scene render channels. Albedo color this is flat color - just your textures without any lighting involved, there is some almost automatic methods to get it, without messing with partitions. I will write it here if you are interested. Not sure what "color channel" you mean, what shader you are using is there any mix nodes in the Surface port? AOV it's just fancy name of render channel I guess )
