Were the Ten Commandments Blue?

Some say that the Ten Commandments were made out of sapphire stone.

- Rough idea of what that would look like

Mainly because of these verses describing how Moses (etc) went up Mount Sinai.

Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel: And they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness. And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink.
- Exodus 24:9-11 (KJV)

But to me that only shows that under God's feet there was sapphire stone. It doesn't conclusively say that the Ten Commandments were made out of sapphire stone.

Blue is also the color by which the Ten Commandments are remembered.

And the Lord spake unto Moses, saying, Speak unto the children of Israel, and bid them that they make them fringes in the borders of their garments throughout their generations, and that they put upon the fringe of the borders a ribband of blue: And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the Lord, and do them; and that ye seek not after your own heart and your own eyes, after which ye use to go a whoring: That ye may remember, and do all my commandments, and be holy unto your God.
- Numbers 15:37-40 (KJV)

But again, this does not conclusively say that the Ten Commandments were blue.

Interestingly enough, the Sunday laws are sometimes referred to as "the blue laws".

So yeah, for me personally, the Ten Commandments were made out of stone (from Mount Sinai).

And the Lord said unto Moses, Hew thee two tables of stone like unto the first: and I will write upon these tables the words that were in the first tables, which thou brakest.
- Exodus 34:1 (KJV)

It clearly says that Moses were to "hew" the two tablets out of stone just like he did with the first two tablets.
