Of all the minor continuity discrepancies between the DCEU movies, one of the most noticeable is the case of Aquaman's eye color. If you missed out on (or skipped) the Whedon cut of Justice League back in 2017, then you are used to the brown yellows closer to Jason Momoa's natural eye color in James Wan's Aquaman. In the 2017 Justice League, Aquaman can be seen with striking baby blues. This coloring was brought back again (or more likely never changed) in the Snyder Cut, leaving some viewers reasonably confused.
As it turns out, this is a choice both directors are very aware of and cite as an artistic difference. But according to Momoa it was a decision motivated by something the actor himself said. In an interview with the Huffington Post promoting Aquaman back in 2018, Momoa revealed about the change, "It was my idea I brought to Zack. I thought it would be rad to have a different eye color. Something that's completely Atlantean that was, like, his mark...I felt like it was just something that would be a little otherworldly, so Zack really liked it."
As for why director James Wan went in a different direction, Momoa said, "I feel like [Wan] wanted to have a warmer thing in this [movie]. I feel like my justification for [the change] is that he kind of went home. He's more rooted, and he's calm when he's around his family."
