The LFBC posted by the White House only has a black stamp. We know it's only black and not multicolored because the safety paper background is green, so a multicolor stamp would be visible.
It does have a raised seal. The seal is visible in the PDF and on the photo taken by Savannah Guthrie.
The State Department does not require the seal be multicolored that’s why they say “or” not “and”.
The seal is not black but consists of raised indentions in the paper caused by embossing tool.
Rides, I think the state department has exceptions for a diety, such as our Dear Leader.
