Hi all, apologies if this is common knowledge. I've got a solid wood reproduction exterior door and jamb I'm painting. Grey on exterior, white on interior.

Does anyone have strong opinions on whether the 1/2" stop surface should get painted white or grey? I have it primed in white but realized the grey face of my door will be touching the white. Not sure if that could rub off on the door over time and should therefore match. Any tips greatly appreciated.
