They indicate the reaction with the solvent that the paper is dipped into.
In your experiment you should have had a few different spots on a base line. One spot should be what your unknown group. And other spots should be what you are trying to match it up with. You should then obtain a suitable solvent and dip the paper with the spots into the solvent. The spots on the base line will rise. You then should comapre your unknown group to your other groups and whichever group traveled the same distance as your unknown group you can match this group to your unknown and your unknown is equal to this group.
Sorry If that is confusing. It was confusing for me when I first did it.
See the related link for a good explanation.
It depends what sort of solution and what sort of chromatography. Assuming it's something simple like ink you'd usually use a piece of paper or filter paper. You'd apply a spot of your analyte (the solution being analysed) at a short distance from the bottom of the paper, then put the paper in a beaker or similar container with a small amount of ethanol, water or another solvent in the bottom. Ensure that the solvent does not go above the level of the spot of analyte. The solvent will be drawn up through the paper by capillary action, and will draw the different parts of the analyte with it and deposit them at different distances from the initial spot. Stop the experiment by removing the paper from the beaker once the solvent front (the horizontal line where the highest wet part of the paper is) reaches the top of the paper.

Chromatography is a method of analyzing the contents of a mixed substance. It is performed by dissolving the substance in a suitable solvent. A drop or spot of the resulting liquid is deposited near the edge of a piece of absorbent paper, such as blotting paper or special chromatography paper. The strip of paper with the spot at the bottom is then suspended over a solvent with the bottom edge of the paper in the solvent. As the solvent soaks upwards, the solvent carries some particles upwards and away from the spot. Different compounds within the mixture will travel at different rates and eventually the strip of paper will show different bands of colors, separating out and indicating some of the various components that were in the original substance. 'Trailing a spot' is a short term for this laboratory process.
Since insoluble dyes do not move with the solvent front during chromatography, they do not have an Rf value. Rf values are only calculated for substances that show movement during chromatography.
GCMS involves running the sample through a mass spectrometer following the data received from chromatography. MS fragments the analytes to show patterns specific to the analyte (and the ionization technique and sector powers) therefore allowing the analyte to be identified. GC is used to separate all volatile substituents of a sample so they can be identified one by one.

Like all modern applications Excel has the capability to show things in various colours, so it can display characters in many colours.
because they doesnot show the absorbane at that nenometer
A variety of materials can be used for this purpose, including litmus paper, chemical reagents, chromatography paper, and spectrophotometers. These materials react in specific ways when exposed to certain substances, allowing for detection and identification.

I feel quite sad about his work due to all the dark colours. Dark colours show sadness and light colours show happiness in artists work🦄🦄☮️
It uses different colours, with a legend telling you which colours represent which height.
If you used a green or red screen, whatever you are looking at being projected would be that colour. Like when you draw with colours you use white paper instead of coloured and when you do use coloured the colours you are drawing with do not show up as well as they would on white.
There are many ways you can show your work when you divide 200 x 20. The easiest way to show your work is to use a pencil and paper. With the pencil record your work onto the paper.
An 8 bit colour display can show 256 colours.
As United's traditional colours are red, white, black, you could paint your nails in these colours to show you like them.
