Silver staining skin - Argyria (colloidal silver)

Hey guys I'm considering using liquid colloidal silver to stain my genitals blue.

You can drink colloidal silver and it will make the skin all over your body go blue (including your internal organs) however I only want to apply it topically to my genitals.

Doctors refer to silver-stained skin and organs as the condition, 'argyria'. Silver is not poisonous and this condition is harmless. Skin goes blue at first and then gradually becomes more like slate grey.

Does anyone here know anything about doing this? I see some Facebook groups about colloidal silver but it seems they're all about using it instead of antibiotics to cure disease. I haven't found any groups yet about staining skin.
