https://en.wikipedia.org/wiki/Red/black_concept describes a notation sometimes used when discussing confidentiality:

  • red denotes signals carrying secret plaintext;
  • black denotes signals carrying ciphertext.

Is there any generally agreed coloring for the analogous integrity question? i.e.:

  • a color which denotes signals where integrity matters (or maybe this is "all of them" and we don't need a specific choice of color); and
  • a color which indicates a signal with cryptographic integrity protection of some kind.

Non-color visual notations also welcome for several reasons:

  1. things still get printed in monochrome;
  2. color vision is not uniform among humans;
  3. using too many color notations at once leads to angry fruit salad rather than clear diagrams.
