man, he is seasick! look at the weather
but seriously:
guess it´s just a bad combination of the daytime and the light conditions that have made the face kind of greenish.
i´ve already warned i´m not good in making screenshots.
So i´ve read you used Pascal´s mods before, i can garantee no change has been made to the colour of the crews skin.
In this update are some changes to the clothing and the hats, but not the faces.
Her´s another screenshot. The guy still doesn´t look very well, but thats a feature, not a bug.

Also he looks fresher than me...
