You can do this with CSS Custom Properties.

Support is pretty good, including Edge (but no IE)

p {
  width:80%;
  margin:1em auto;
  text-shadow: 2px 6px 2px grey;
}

p.colored {
  color: var(--mycolor)
}

p.shadowed {
  text-shadow: 2px 6px 2px var(--shadowcolor);
}

<p class="colored" style="--mycolor:red;">Lorem ipsum, dolor sit amet consectetur adipisicing elit. Quibusdam numquam aut aperiam excepturi id quaerat, fugiat, impedit natus maxime voluptates officia? Fuga earum quis exercitationem et fugiat, amet nam officiis?</p>

<p class="shadowed" style="--shadowcolor:green;">Lorem ipsum, dolor sit amet consectetur adipisicing elit. Quibusdam numquam aut aperiam excepturi id quaerat, fugiat, impedit natus maxime voluptates officia? Fuga earum quis exercitationem et fugiat, amet nam officiis?</p>
