Unless, otherwise, maybe, perhaps - widespread retina failure has occurred - the jumpers were decidedly *pink* on my telly too.
And without any possibility of a notion against the absolute, the question of jumper colour has much todo with the reflective material being chosen. Not necessarily just a camera on a bright sunny day, even though Red as correctly put forward, is volatile to broadcast. However, it's not that volatile as when have you ever seen St Kilda or Swans jumper looking a tad pink in the reds? Probably never.
Maybe it was a choice in relation to a Cancer foundation Pink Lady day?
However, as Mono put it it's 'most disappointing'. And not a 'whinge' to want your team's colours to be true to their origins and consistent.
Kind Regards
