Loop random numbers for a switch case up to n times

i´m getting crazy with this...I need to loop 10 times (automaticaly) a random number between 1-4 (both included), and this numbers must obtain a colour from switch cases', printed in the console.I tried to separate the switch cases, random function & the loop of that random function but....Any suggest???

//colours to assiged(depending on random number)
function getColor(colorNumber=0)
{
   colorNumber = parseInt(colorNumber);
   switch(colorNumber){
       case 1: return "red"; 
               break;
       case 2: return "yellow"; 
               break;
       case 3: return "blue"; 
               break;
       case 4: return "green"; 
               break;
       default: return "black"; 
                break;
   }
}
//var with random generated
function getAllStudentColors(){
   var getAllStudentColors = Math.floor(Math.random(4-1)*10) + 1;
   }
//looping for function of random numbers
function loop() {    
var exampleColor = 0;
   while (exampleColor = 1) {
       getAllStudentColors();
       exampleColor++;
   }
}
var exampleColor = getColor();
getAllStudentColors();
