Ошибка E0137 Выражение должно быть допустимым для изменения левосторонним значением

for (int i = 0; i < 50000; i++) {
    Bomb b;
    b.weight = rand() % 100;
    b.color = "red"; // Ошибка E0137
    b.tnt = rand() % 1000;
    bombs.push_back(b);
} 

При b.color == "red"; ошибка исчезает, но слово "red" в консоль не выводится. Можете, пожалуйста, помочь решить данную проблему.
