Luciana Contartese

Hello everyone! So, when watching some series, I noticed the skin looked yellowish in an unnatural way. Do you think this happened because the makeup artist chose the incorrect undertone for the actors? Or it might be the type of lighting/colour temperature of the lights? I can also tell the makeup is only applied on the face and not on the neck, but that's a discussion for a makeup related forum I guess ? Thanks in advance.
