Then, after having dried the strip one could very scarcely identify two distinct colors, each only a couple of millimeters away of each other: Teacher Glen then gave us a scale upon which we should identify each pigment strip with its individual color, measure its distance in relation to the origin the first line drawn with the filtrate and then calculate the REF.

First one had to identify the precise color of each, this was a bit problematic, due to the gamut of different tones present. As presented in figure 1 or Data Table 2, there is a set order of the distribution of each color band.

The REF was calculated upon the following formula: The yellowish green Chlorophyll B was the first band we identified, only migrated mm and the bluish green Chlorophyll A migrated mm. This told us that there was only Chlorophyll present in the green leave, although other students who had performed this experiment as well achieved different results.
