dimmer-adjustment-mode :foreground
In :foreground
mode a larger fraction causes the font color to be
increasingly similar to the background. (A larger negative fraction
causes the opposite to happen. The font color will be increasingly
different from the background.)

mode a larger fraction causes the background color and
the foreground color to move closer together. (A larger negative
fraction causes the background and foreground colors to move farther
apart from one another.)
