BoM - entries have color-difference?

Are there any meaning to the text-color-changes in the 3d-printed BoM-list ? They are, as far as I can see, not explained - are they important ? Do they provide the same flux in colors, as the overview example, if printed ? Im halfway through the printprocess and just noticed this…

That is just how I color-code my printed parts that I sell. Some people wanted to know how I did it and that was how I kept track.
