Because most black inks are made up of more than one colour. When the ink gets wet, the colours separate.
The evidence that exists that marker ink is a mixture is that the ink can be separated into black and other color pigments. This can be done on filter paper by dotting the marker just above the edge and adding ethyl alcohol, which drags the pigments separately across the paper.

When you mix water with ink, the bubbles will go down to the bottom of the bottle and spin around. It may change colours like yellow, green, red or blue. There is no answer for this. It will make a interesting chemical reaction. Scientists are looking for a solution.
Sand is not soluble in ink.
To determine the colors in black biro ink, you can use chromatography, a method that separates the components of a mixture. By applying a small amount of the ink onto a piece of chromatography paper and then placing it in a solvent (like alcohol), the different dye components will travel at different rates, separating into distinct color bands. This technique reveals the various colors that make up the black ink.
Biro ink and chlorophyll are soluble in methylated spirits
a quill pen has mor ink than a biro
yes a biro is man made the ink is man made and the pen itself is manmade
Ladislao Biro was working as a journalist when he found that the newspaper ink was smudge-free. So he started to work with his brother, Georg, to create the Biro.

The ink in a ballpoint pen (biro) is typically composed of dye or pigment suspended in a solvent such as water or oil. The specific composition can vary depending on the manufacturer and type of pen.
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.
Black biro ink typically consists of a mixture of black, blue, and purple color pigments. These colors combine to create the dark and rich black color commonly seen in biro pens.
To unblock ink in a biro, start by gently shaking the pen to mix the ink. If that doesn't work, try scribbling on a piece of paper to encourage the ink flow. You can also try placing the pen tip in warm water for a few minutes to dissolve any dried ink. If the problem persists, consider replacing the ink cartridge or the entire pen.
