When the Temple was still standing in Jerusalem, every Yom Kippur the priests would take the crimson thread that held the scapegoat and tied it to the temple door. When God accepted the atonement sacrifice, the thread would turn white. Look what the Babylonian Talmud says about the last years of the temple:

"Our rabbis taught: During the last forty years before the destruction of the Temple the lot ['For the Lord'] did not come up in the right hand; nor did the crimson-colored strap become white; nor did the western most light shine; and the doors of the Hekel [Temple] would open by themselves"
-Babylonian Talmud, Soncino version, Yoma 39b

The temple was destroyed in 70 AD, Christ was crucified in 30 AD.
