PC: Newton Discovers Fraunhofer Lines

OK, so I thought I'd put a claim made by Degrasse Tyson on Cosmos up for the board -- could Issac Newton have performed the necessary experiments (looking at the light from a prism with a telescope) and analysis to recognize a fraunhofer spectrum? If so, what impact would that have?
 
All I know is that he made violet a special color on his spectrum solely because he liked 7, when it is really only purple.

Other than that, it's science, so you may not get many responses.
 
I'm not sure it would have any obvious effects. If I understand correctly (not certain, by any means) they were just a curiousity until after Angstrom's work identifying the emission spectra of heated gases. So I suppose he could have seen them, but they would have been a curiousity at best. They were noticed years before Fraunhofer rediscovered them and paid attention to them, after all.
 
The short answer is of course he could. However this is more likely to be done in his weird alchemist phase rather than when he was being a "proper" scientist (and yes I know there wasn't a division between the two in his life time) so as it did not lead to the philosophers stone it would have been described and left for others to investigate.
So it probably wouldn't have made a great deal of difference.
