Checked it in-game, yeah it's the same with the green wake in the intros and outros.
Obviously it's not the end of the world but shame such a simple oversight was made...
But then again it wouldn't be the first simple oversight with Klassic Jade, after all if you use the costumes for Kitana and Skarlet with the black accents, their masks remain in their primary colour. Use Jade's and for some reason it's black. Which is a shame because they all look much nicer with that bit of contrasting black texturing; less tacky and cosplay-esque in such a realistic looking game.
So if you want them all with the black accents, Jade gets a black mask.
Use them all in the single plain colours and I think Skarlet in particular comes off looking a bit under-designed, as combined with red hair she's just too devoid of any contrast (Jade and Kitana at least have their black hair to mix it up).
Can't win either way... so have got Kitana and Jade in plain, whilst Skarlet has the black accents. And it sort of annoys me haha.
Sorry that's probably pure OCD talking haha, but with a costume pack like that I do want them to look like a uniformed team of Outworld assassins. The fact that the mask looks almost black in the 'Masks' menu for Jade by default surely must have alerted someone to the issue?! Surely?
