.text-primary {
  color: primary;
}

.text-secondary {
  color: secondary;

/* my-component.css */
@value colors: "./colors.css";
@value primary, secondary from colors;
@value small as bp-small, large as bp-large from "./breakpoints.css";

.header {
  composes: text-primary from colors;
  box-shadow: 0 0 10px secondary;
}

@media bp-small {
  .header {
    box-shadow: 0 0 4px secondary;
  }
}
@media bp-large {
  .header {
    box-shadow: 0 0 20px secondary;
  }
}

Note that the : in a @value definition is optional as to not break Sass.
