Where does this idiom come from?
Paper, la carta, is (more often than not) white. Ink is (more often than not) a dark color, either black or blue. When you write something black on white, it basically means that you are writing it down. This contrast of colors also has another meaning: black on white is clearly visible. The writer is not trying to hide any lies.
