In my opinion your going to need to take white and mix a little black in for grey. However there is another technique used by myself and other artists, which is simply diluting the black with purified water. the mix can start at 50/50 but you will find that is very dark still. i have cut black down to 15water 1 part black and achieved a very nice subtle ghosty grey.
Sometimes the grey your looking for can only be created by dilution . The downfall is it takes a somewhat experienced artist to deal with the thinner ink. Mixing with white allows you to retain the same consistency which makes it easier. Again though, it makes a "brighter" grey. Brighter greys can quickly turn a nice black and grey piece into a disaster by not blending AT ALL with traditional black and grey wash style tattooing. Of course you can avoid all this and just buy a 6 pack of grey wash shades at Element tattoo supply. I get alot of stuff from them and they rock. Happy Tattooing!!

Hand Tapping or simply tattooing by hand or tattooing without electricity
No, you should only use ink specified for tattooing. Any other type of ink may not be compatible with skin and could cause infection.
water is used in tattooing to thin down black ink to do grey shades, it is also used to clean the inks from the needels when changing colors
rubbing alcohol works for tattooing
When Coloring use very small circles. and when shading use a flicking motion away from the outline.
its called a wash you use your black ink put it in your ink cap add few drops of distilled water this is called grey-wash depending on amount of water added ,with less your color will be darker with more it will be lighter .
you can use a soft cloth, cotton preferred. or soft paper towels. NOTHING HARSH!
you need to put it in the wash with grey or black clothes or materials .
Regulations for tattooing vary by state and city. Check your local government.
