비트 마스크에서 red,green 추출이 잘 안됩니다.

unsigned int pixel_color = 0xDAA520;

cout << "pixel_color : " << bitset<32>(pixel_color) << endl;

//

const unsigned char red_mask = 0xFF0000;

const unsigned char green_mask = 0x00FF00;

const unsigned char blue_mask = 0x0000ff;

unsigned char red, green, blue;

blue = pixel_color & blue_mask;

cout << "blue_color : " << bitset<8>(blue) <<" " << int(blue) <<endl;

green = (pixel_color & green_mask)>>8;

cout << "green_color : " << bitset<8>(green) << " " << int(green) << endl;

red = (pixel_color & red_mask) >> 16;

cout << "red_color : " << bitset<8>(red) << " " << int(red) << endl;

이렇게 코드 작성했는데 blue는 잘 추출되지만 red랑 green은 0으로 추출됩니다.ㅠㅠ shift연산자 잘 한거 같은데 왜 0인지 모르겠습니다.
