you have various errors

  1. you've 2 functions called changecolor, functions must have unique names

  2. svg not use color colour elements, instead uses fill (and stroke).

  3. id values must unique, want replace id class , use getelementsbyclassname instead of getelementbyid. if you'll need cope more 1 element though. i've not completed part, should try understand what's going on.

i've removed 1 id version can see working on left eye.

document.getelementbyid("test").onmouseover = function(){changecolor()};    function changecolor() {  document.getelementbyid("test").style.fill = "red";  }    document.getelementbyid("test").onmouseout = function(){changecolor2()};    function changecolor2() {  document.getelementbyid("test").style.fill = "green";  }
