OK. Just to clear this up once and for all!
The Blackbird is, in fact... INDIGO BLUE
The paint code is "FS35402 Indigo Blue"
They are indigo blue on the ground. They are indigo blue in the sky. They are indigo blue when hot. They are indigo blue when cold.
The colour actually comes from tiny Iron beads in the paint used to absorb radio waves (radar). They also have the beneficial property of acting as a heat sink for the airframe. If you ever get to see an SR-71, feel it. It's rough - that's the iron beads.
