/* Thanks Chris Eppstein for simplifying my code! */
/* Testing our new function */
body {
background: gray(50%);
background: gray(255, .2);
}
/* Test should output something like: */
body {
background: #7f7f7f;
background: rgba(255, 255, 255, 0.2); }

I like the more mentally pleasing way of calling out gray in percentages. Fancy. :D

This can be simplified to:

@function gray($intensity, $alpha: 1) {
  @return rgba($intensity, $intensity, $intensity, $alpha);
}

Which will return a Sass color resulting in:

body {
  background: #7f7f7f;
  background: rgba(255, 255, 255, 0.2); }

Man I've been defining a grey function in all my projects for three years. Now that it's gray I'm screwed :D

The Stylus version of this is almost identical:

gray(intensity, alpha = 1)
  rgba(intensity, intensity, intensity, alpha)
