Olive Oil or any Oil does not contribute to the purple color.
The scientific facts are that solvents and Carbon 60 molecules exhibit different colors.
In this experiment, the color of the C60 solution in both the toluene and xylene solvents turned purple, and it was a darker purple in the TCE (Trichloroethylene), as seen in Figure 2.

Conclusions The results of the study of the series of C60 samples prepared by various methods allowed us to draw the following conclusions. (1) The molecules of solvent are not incorporated into the crystal lattice of C60, but rather are adsorbed at the interfaces of microcrystals. (2) “Sintering” of the microcrystals upon heating is assumed to be responsible for entrapping some of the solvent molecules in the sample. This may be the reason solvents cannot be completely removed by vacuum heating of samples of C60...
