Can blue painter's tape turn glass blue if left on too long?

Question

A yokel told me that the blue painter's tape can be permanent. He heard of someone leaving it on the window pane too long ( like a year ) and it turned the glass blue. Is there any merit to this yokel?

Answer 1

Glass is inert and impermeable, so no merit to the yokel's claim that it turned the glass blue.

That said, like most tape, it can dry out and leave a residue over time. Which can typically be easily scraped off.
