Amber HeardAmber Heard shared a photo on Twitter of herself suited up for "Aquaman," saying "Meet Mera. Day 1." Director James Wan shared an equally stunning photo of the now red-haired actress as the sea goddess, aka Queen of Atlantis and Aquaman (Jason Momoa)'s wife.

Unless the color palette changes dramatically in the final film, Wan's movie already looks a lot more colorful than the blue-and-gray tones of the same character in Zack Snyder's "Justice League."

"Aquaman" opens on December 21, 2018. "Justice League" hits theaters on November 17, 2017.

Is it just us, or does Heard's look here remind you of Batman villain Poison Ivy?

The actress also shared a photo on Instagram of herself in the make-up trailer while reading, natch, an Aquaman comic book.

Day 1 of we go! #aquaman
