Options

preserve

The preserve option determines whether the original gray() function should be preserved or replaced. By default, the gray() function is replaced.

By setting preserve to true, the original gray() function is preserved.

postcssGray({ preserve: true });

body {
  background-color: gray(100);
  color: gray(0 / 90%);
}

/* becomes */

body {
  background-color: gray(100);
  background-color: rgb(255,255,255);
  color: gray(0 / 90%);
  color: rgba(0,0,0,.9);
}
