Colors blended in inks cannot be separated once mixed. The process of color separation involves digitally breaking down the colors into separate plates for printing. This separation allows each color to be printed individually to recreate the original blend.
One way to separate the colors blended in ink is through chromatography. This technique uses a solvent to move the ink across a medium, causing different components to separate based on their solubility. Another method is through distillation, where the ink is heated to separate the components based on their boiling points.
This question is not very precise, but I assume you mean which colours will not be separated by chromatography. It is not a property of the colour, but of the substance you are trying to split up. Chromatography only works if the substance is soluble in the liquid you are using to run the chromatogram. Thus some black fountain pen inks separate in water, but the ink from a ball point pen usually does not.
Black is actually an ABSENCE of light- or of color. There are no primary pigments or colors that can be blended to produce black. The pigments used in black paint are frequently either carbon black, or black iron oxide.
It depends on what you're mixing. With light, you'd get white. With paints, you'd get brown. With printer inks, you'd get black.
Naphtol crimson is typically a blend of pigments PR112 (Naphthol AS-D Red) and PR170 (Naphthol Red). These two pigments are combined in varying proportions to achieve the desired shade of crimson.
All of them.
Red and white make pink.

Create new colors by mixing ready-made liquid inks. With a little practice, you can learn which colors to mix to make new colors or how to dilute colors to make them lighter. This will allow you more color choices without having to purchase etc.

Red and blue to make purple, then add some pink and mix in white, until it is pale enough of a purple, to be a good excuse for violet :) hope this helps

Iron gall ink is a black ink made from iron salts and tannic acids, typically from oak tree galls. But I do not believe tannin was ever used. However one could make an ink like material based on iron salts and tannin. However such inks are very bad, being acidic they attack the paper and can eventually "burn" holes in the paper whenever the ink was applied. There are much better inks and inks of a wide range of colors now.
There are several brands of ink on the market, and lots of different colors to choose from. I personally use Eternal and Intenze inks, and there are a huge assortment of reds in the sets, and if none are exactly right, then a good tattoo artist should be able to use color theory to figure out exactly what mixes should be used.
Black and white makes brown
