how do you get the color on the chromatograph
For example, in paper chromatography water is the mobile phase and paper is the stationary phase. The solution's components ideally move at different speeds as they travel through the stationary phase so that they can be separated. Take one of the paper towel strips you prepared and place the pencil line you drew on top of the now-colored drop of water. Do you see the dye soak into the strip, coloring the area around the line? You can get some extra dye on the line by dabbing the sides of the wet candy with it.
