the alloy that's secretly mostly copper, faking it as brass with a blush.
means Red brass is a copper-zinc alloy with a high copper content (roughly 85% copper), giving it a warm reddish-gold color rather than the yellow of ordinary brass.
from "Brass" comes from Old English "bræs," a word for the copper alloy whose deeper roots are obscure — it has no clear cousins in other Germanic tongues, making it something of an etymological orphan. "Red" is the plain English color word, here flagging the alloy's coppery blush; the more copper in the mix, the redder it runs, so metalworkers simply named it for what their eyes told them.
