My first thought was no way they will do red/black eyes all the time.
But look at Deadpool. It seems he will be with burned skin in movie much longer then with normal.
It would be awesome if Liman would be able to make red eyes work for sexy thriller. Mayve they need to change the contrast of eyes through movie, like very red/slightly red but still red
As far as I can see they have options:
1. Red and Black (practical) - This can be done through the use of a full eye contact. Only issue is, they can be very uncomfortable for the actor.
2. Red and Black (CGI) - The can render the eyes to be red and black. Probably wont look the best though.
3. Red and Black (50/50) - A red contact and render the whites of his eyes to black via CGI. In terms of the look, it can go either way.
4. Red and White- Just have red eyes via contacts. It grounds the movie, doesnt take away attention from Tatum's money maker (his face lol)
5. Plain ol eyes, only red in flashes during action scenes (similar to how they worked Storm in the movies)
Once they figure out what they are going to do with the eyes, the next question is, how are they going to treat them. He cant very well walk around in broad daylight in full Gambit glory. The 5th option plays well with this reality. To save on plot holes and Tatum's eyes while staying true to Gambit, they can say his eyes are truly Red on Black but GAMBIT (the character) is wearing special full eye contacts that make his eyes appear to be normal. They can save Tatum (the actor) from wearing the uncomfortable lens' all the time, only having them in possibly at the beginning, a small section in the middle and at the end during the movies climax for whatever final showdown or endgame they may have planned, where he will have lost his coat, his clothes are all torn to shreds, his staff is broken and he's all out of cards (much to the delight of female fandom). If all goes according to plan and Liman is allowed to make a movie he wants, we may have the "Captain America: Winter Soldier" equivalent for Fox's X-Men line.
