How to get the color space type from an image/view

typedef rgb8_image_t image_t;
typedef typename color_space_type<image_t::view_t::value_type>::type colour_space_t;

There are rgb8_pixel_t, bgr8_pixel_t, and any other number of combinations. So how do you get the red channel value

auto get_red(pixel_t p)
{
    return get_color(p, red_t());
}
