Someone needs to address this Infinity War problem

Alright! Someone needs to address this Infinity War problem. In the after-credit scene, Nick Fury and Maria Hill try to do a Bat signal thingamabob to Captain Marvel as they die before dropping it, letting us see the screen. On the screen, you see this. This is weird. In Captain Marvel photos, the Captain Marvel costume is green and black.
Why is the Bat signal blue and red, like the traditional costume, yet the set photos are green and black? Does she change her costume after one movie? All the leaked merch is blue and red, too.
(I  like the red and blue one better).
The typical Kree costumes are technically green, black, and white, so is this a Kree costume? I don't know and don't want to wait until 2019 to find out!
Traditional comic Marvel costumes are awesome!*







*Not counting Wolverine, Hawkeye, Scarlet Witch, Captain America, the X-Men, Thor, ehh... never mind. Marvel costumes suck sometimes.
