Reply To: Techeiles 🔵❎🐌☑️🐟

First of all, not all Rishonim had complete access to Yerushalmi. Granted Tosfos agreed that the Bavli is mashma blue, but that is in a vacuum, meaning that it’s more logical that the Bavli means blue than green. But once you have the Yerushalmi, we have a problem: There cannot be a machlokes as to what color Techeiles is as I have explained earlier. But for some reason the Yerushalmi decided to describe it differently than the Bavli. So now you either have to fit the Bavli into the Yerushalmi’s description or the Yerushalmi into the Bavli’s description. Now to interpret the Bavli as green is less logical than to interpret it as blue. Whereas to interpret the Yerushalmi as blue is illogical. So head to haed it seems like a much better option to say that Techeiles is green.

As for the fact that the Gra changed the girsa, that is completely irrelevant because no one else does and Tosfos quotes the girsa as is.

So now you can probably understand why I have a hard time understanding the Rishonim who say that Techeiles is blue unless they address the Yerushalmi which they don’t.
