It's been previously noted by Halo's Transmedia boss Kiki Wolfkill how the live-action series won't be 'core-canon'. It's being referred to as "Halo Silver" - meaning it exists in its own timeline and will not impact other Halo media, like the games or books. And it's being done to "protect" the series.
Despite this, it seems not everyone is happy with the look of Cortana (played by Jen Taylor, the video game voice of Cortana) in this particular timeline - with many calling for a version of her that's blue, or at least "bluer" than she is now. An alternative colour request is purple - a throwback to Cortana's younger years.

And others on social media agree - while some don't, suggesting Cortana is already blue enough in the trailer:
