Not more than two colors of the same color

I call a method to get random colors to eight objects. If the color is the same for three objects in a row, then it's not valid. Only one or two colors besides each other of the same color is valid. I thought my code should work, but I still get three objects in a row of eight with the sam color! What have I done wrong? perhaps it could be done in a better and simplier way? Proposals are welcome!

Part of the loop to get eight random numbers

for (int j = 0; j < 8; j++) { // 8 objects in each column

// Call method to get random color
int color = getRandomColor(j);

The Method

public int getRandomColor(int j) {

    int color = randomNumber1.nextInt(8);

    colors[j] = color;
    if(j>1 && colors[j-1] == color && colors[j-2] == color) {
        getRandomColor(j);
    }
    return color;
}

Try this:

public int getRandomColor(int j){
  int color = randomNumber1.nextInt(8);
  colors[j] = color;

  while(j>1 && colors[j-1] == color && colors[j-2] == color){
    color = randomNumber1.nextInt(8);
    colors[j] = color;
  }
return color;
}
