Reply To: Techeiles 🔵❎🐌☑️🐟

I don’t think the pesukim indicate that they are the exact same color. The prefix ? can mean that they are similar but not exact. Since the Bavli does not compare Techeiles directly to the Rakia, there is no Mefurash Bavli. Also according to you why does the Gemara bring in Yam? (You could answer like Rashi that Techeiles is not so similar to Rakia but it is to Yam, but then there would be no Mefurash Bavli.) Maybe you will try to answer that even though the Yam serves no purpose in identifying the color,the Gemara wanted to bring bring it in for the symbolism of the nisim done at the sea (which Rashi mentions), but then the Gemara should have said that Techeiles is Domeh L’yam and Domeh L’rakia. But that’s not what it said. So if anything, there’s a mefurash Bavli that Techeiles is not directly Domeh L’rakia.

And again, you can’t disregard the Yerushalmi, it has to fit in with the Bavli.
