    (The dust clouds absorb the blue light while letting the red and infrared light pass almost freely)

    That is because most of the stars visible in that area are in front of the dark dust clouds. In the infrared this stars look bluer than the others, while the few dim ones that we can see behind the dust are almost completely red.
