You are probably referring to chromatography, if that is the case here is the explanation.
The components of the dye in question are all soluble in the alcohol, however the extent of this solubility is not the same for each individual substance. As the alcohol dissolves the dye and moves up the paper strip, it gradually begins to evaporate off the paper. When alcohol is evaporated, molecules that are less soluble in the alcohol will be forced out of solution and deposite onto the paper permanently. The longer the strip of paper and the longer the solvent front is allowed to move up the greater the extent of the separation of compounds, however they will always travel the same distance defined by the ration of the length the substance traveled compared to the length the solvent was allowed to travel. By using this method chemicals are identified based on how far they traveled.

What is the liquid in a magic eight ball?
The liquid in a magic eight ball is typically a dark dye mixed with water or alcohol. The dye helps to obscure the white plastic dice inside that float to reveal the answers to your questions.
How do you separate the different colours in a fabric dye?
Different colors in fabric dye can be separated by a process called chromatography. In this process, the fabric dye is dissolved in a solvent and then the mixture is allowed to move up a strip of paper. As the solvent moves up the paper, different colors in the dye will separate and appear as distinct bands.
Why do they add red dye to colorless alcohol in thermometer?
The red dye is added to make it easier to read the temperature scale on the thermometer. The dye provides a contrast against the clear liquid, making it more visible and accurate to read the temperature markings.
What happens to a leaf when placed in the alcohol and what the alcohol removed from it?
When a leaf is placed in alcohol, the alcohol acts as a solvent and removes the chlorophyll from the leaf, causing it to lose its green color. Other pigments present in the leaf may remain, giving the leaf a different color appearance.
Can rubbing alcohol stain fabric?
Yes, rubbing alcohol can stain fabric by removing the dye or color from the fabric. It is important to be cautious when using rubbing alcohol on fabric and test it in an inconspicuous area first.
How do you separate blue dye and red dye?
Chromatography-This is when you put dye on a piece of special paper and put it in some water. When the water is soak up the dye will separate.
Why does lipids have to be placed in alcohol first before being placed water?
it has to be placed in alcohol first because lipids are soluble in alcohol but not in water.
Crystals of dye are placed in water?
When crystals of dye are placed in water, they will dissolve if the dye is soluble. The dye molecules will disperse in the water, creating a colored solution. If the dye is insoluble, the crystals will remain visible in the water.
What is inside rubbing alcohol?
Rubbing alcohol contain water, methanol or isopropyl alcohol, a dye.
Can rubbing Alcohol dye your hair?
No, it cannot.
How do you separate dye to blue ink?
To separate dye into blue ink, you would need to use a process called chromatography. This involves dissolving the ink in a solvent and allowing it to separate based on the different properties of the dye molecules. The blue dye will travel at different rates along the chromatography paper, allowing you to isolate it as a distinct color.
How can you separate blue dye from a cloth?
In runescape, you can't.
What is the method to separate dye from blue ink?
Chromatography
