A single word connects these images:
What is the word, and what are the connections?
The word might be:
Hangar => coat hanger
Waste => waistcoat
Arms => coat of arms
Turn => turncoat
Tail => tailcoat
Medieval rack => coat rack
Rain => raincoat
Paint => coat of paint
Laboratory => labcoat
A coat covers surfaces.
My guess is:
Hangar -> Black Hangar Studios (film studio)
Waste -> Blackwater (waste water)
Arms -> Blackarm (cotton disease)
Turn Back -> Turn Black? Black Turn: Operation Barbarossa?
Lemur Tail -> Black Lemur
Medieval Rack -> Black Death (during medieval period)
Rain -> Black Rain (action thriller or music album)
Paint -> Paint it Black (song)
Science Lab -> Black Mesa (Half-Life series)
As for the title:
When your eyes are covered, all you see is black.
