Which color you think will go better with her eyes? I can't change the background but I may change the color of her clothing if it makes her look better.
Hmm... meant my eyes, but going forward... how about (feel free to disagree):
- lime green
- grass green
- faded green
or
something like a white that melds into sky blue/ocean blue?
Edit: Thought about it for a bit and here's some reasoning...
You want your characters to stand out in some way, to give them a trait that identifies them as someone of importance. Dressing them in the same color as the background does not do that unless you redeem them in some other way.
Sure, we know the character here is important, but that's because it's a woman in a 3d-rendered porn game. Adding background characters with the sole purpose of being a filler is a lot of work and takes a lot of time.
To attract attention through visual triggers, you usually use contrasting colors. The background is warm, dress the character in cold color and reverse - it's how it usually goes.
The second thing is balancing colors. This character's eyes are smothered into the background at the moment since i barely realized they even had a color...
Thus, the relationship between colors needs fine tuning so that neither element which you wish to present is thrust into the background instead.
What this means here is for a warm-colored background, use a cold-colored clothing that balances out with the cold-colored eyes. Faded green or sky bluish/white-to-blue are my choices right now.
