It is rather simple really. If there are silver compounds in the blood they are light sensitive, and will produce silver atoms upon exposure to light (basic photography). Thus one can get a buildup of metallic silver atoms in the skin when exposed to sunlight if they have silver compounds in the blood. Normally these get transported out in short order with no lasting effect. However if the blood contains sufficient silver compounds, and there is any developer in the blood (most likely caffine), then additional silver will plate out on these seed atoms of silver, creating silver crystals (basic photo developing). At some point these crystals will grow to sufficient size and shape, to where they get stuck in the tissues. When they grow to sufficient size, then they will begin absorbing light, and will then appear as a gray, blue or black area.
Thus to get argyria requires sufficient silver compounds in the blood, or skin (you can get it instantly with silver nitrate applied to the skin then exposed to light). Colloidal silver should not be capable of causing argyria since it will not reduce to silver metal causing particles in the skin to grow, it is already silver metal. Theorectically the ionic portion of CS could contribute to this condition, but there are two things that will tend to prevent it. First, the ppm of the silver will be too low to cause the crystals to grow rapidly engough to get trapped. Second, all the colloidal portion of the CS will provide sites for any plating out of the ions, thus they will not tend to do so only in the skin where it can be seen, and the particles will not grow sufficiently to get trapped.
