  Test case for JDK-8292276
  
  Adds a jtreg test case that fails before JDK-8292276 patch and passes after.
  Test the Cyan color name.
  Cyan is the missing color name that originates the PR JDK8292276 : Missing Color NamesIn CSS.
  Cyan name, as most color names Colors defined in CSS Color Module Level 4, is not referenced in CSS.java.
  This test fails, if getAttribute doesn't return a cyan Color Object.
  When a color name is missing getAttribute returns a black Color Object.
