The flag of the Democratic and Popular Republic of Algeria is constituted by a green and white rectangle embossed by a red star and a red crescent.
Editor's note: I could not find an original scan of the relevant law online, and so rely on
an archived page from the Permanent Mission of Algeria to the UN, courtesy
of Flags of the World.
Despite pouring over Rood's work, I could not figure how to interpret
the color instructions provided. The Pantone colors here are used
across most supplementary sources. (Interestingly, the one source
I could reference directly – the London Olympic manual – has placed the star
in the wrong place!)
