How to pass option into HTML select

I want different behaviors depending on which <option> element is selected:

<select name="colorSelector" onchange="handleColorChange();">
     <option value="">- select -</option>
     <option value="1">Red</option>
     <option value="2">Blue</option>
 </select>
 
 function handleColorChange() {
     // Behave different depending on which <option> was just selected
 }
 

What do I need to pass into the handleColorChange() method from inside the onchange listener in order to accomplish this?
