Because its not all the same colour so it travels up the paper and then you can see what the answer it :)
I'm a high level student in science and ca answer and questions you ask me :)
Pigments are not carried up filter paper, dyes are. But they are carried up in solvents.
Pigments are carried up the filter paper during chromatography due to a combination of their solubility in the solvent and their interaction with the paper. As the solvent moves up the paper by capillary action, it dissolves the pigments and transports them along with it. Different pigments have varying affinities for the paper and the solvent, causing them to travel different distances, which allows for their separation and identification. This process relies on the principles of differential migration based on polarity and solubility.
It depend on the density of the pigments.

Different pigments absorb light of different wavelengths.
Different pigments respond to different wavelengths of visible light.

Pigments move at different rates in chromatography because they have varying molecular weights, sizes, and polarities. Lighter, less polar pigments travel faster because they interact less with the stationary phase and are carried further by the mobile phase. Heavier, more polar pigments move more slowly as they have stronger interactions with the stationary phase.

Very fine sediments that can be carried by wind over long distances are known as dust particles or dust clouds. These particles can range in size from clay to silt and are light enough to be lifted and transported by wind currents for extended distances. They can have significant impacts on environmental and health issues when carried over long distances.
from different pigments!
Chromatography is the laboratory technique used to separate the different pigments in a green leaf. The leaf pigments are separated based on their solubility in the solvent used. By analyzing the bands of separated pigments, researchers can identify and quantify the different pigments present in a leaf.
