How do you separate dyes of different colors in black ink?
One method to separate dyes of different colors in black ink is through a process called chromatography. In chromatography, the ink sample is placed on a material that allows the dyes to move at different rates, based on their chemical properties. As the dyes separate, they can be visually distinguished by the bands of different colors they produce on the material.

Why azoic dyes are limited in range of shades?
Azoic dyes are limited in range of shades because they are derived from specific chemical compounds that have a fixed color range. These dyes are produced by coupling diazonium salts with specific aromatic compounds, resulting in a limited selection of colors that can be achieved. Additionally, the chemical structure of azoic dyes limits their ability to produce a wide variety of shades compared to other types of dyes.

Why do instructions on henna hair dye warn against using it if you dye your hair with chemical dyes can it be harmful or just produce a funny colour?
Henna dyes and metallic dyes are bad both ways. They can interact with other chemicals to create colors with an odd greenish/orange cast and/or damage to the point of needing to be cut off. I do not recommend henna dyes, do some internet research...you'll probably find some of what I'm talking about. -------------- Metallic dyes and henna dyes (which usually contain metallic dyes) cannot be removed from the hair. Once you have used a metallic dye, no other chemicals can be used on the hair. The only way to remove the color is to cut off the treated hair. Using other chemicals on hair treated with metallic dyes can cause negative chemical reactions that may include irreversable damage and breakage, uncorrectable unusual color changes, and even chemical burns. One of the tell-tale signs hair has been treated with a metallic dye is when any ammonia-based hair color product or bleach is applied, the hair begins to emit a strong foul odor and smoke may be seen rising from the hair. If this occurs, rinse immediately to prevent chemical burns on the scalp and minimize damage to the hair.
