Prussian Blue is the color used for blueprints. It is called Midnight Blue in a box of crayons. It isn't just a color, though. The material that makes the pigment can also be used as an antidote for certain kinds of poisoning, as laundry bluing, and as a stain to detect iron in bone marrow biopsy samples. It cannot correctly be displayed on computer screens but understanding why is for the advanced class.
Even CLOSER to isolating that thumb!
