Short JavaScript version

Inspired by Valen's answer:

v=c=>((s=document.head.style).color=c,q=s.color,s.color='',!!q);
// v('red') => true
// v('reeeed') => false

More readably:

const validColor = c => {
  document.head.style.color = c;
  const q = document.head.style.color;
  document.head.style.color = '';
  return !!q
};
