No foreground color, and no font.

"Empty face" is the standard notion. Here's an example how it's used:
1. M-x make-empty-face RET foo RET
2. M-x customize-face RET foo RET
Then output is:
Hide Foo face: [sample]
State : NO CUSTOMIZATION DATA; not intended to be customized.
nil
-- Empty face --

Because they will cause the same problem as with display-time-date-and-time,
except that other faces are used less often, so it will take time until users
will notice these problems.
