    for (int i=0; i<response.length(); i++){
        Customer customer = new Customer(response.getJSONObject(i));
        customer.setInitBackground(Util.getAvatarColor(activity).get(Your suggestion));
        activity.customers.add(customer);
    }
} catch (JSONException e) {
   e.printStackTrace();
}

Here's the solution. Thank you to all answers.

try {
    for (int i=0; i<response.length(); i++){
        Customer customer = new Customer(response.getJSONObject(i));
        int pos = i % Util.getAvatarColor(activity).size();
        customer.setInitBackground(Util.getAvatarColor(activity).get(pos));
        activity.customers.add(customer);
    }
} catch (JSONException e) {
   e.printStackTrace();
}

You have to use hashes limited by the number of colors.

Contact contact = getItem(position);
int pos = contact.getName().hashCode() % colors.length;
int color = colors[pos];
