Unfortunately, the interior designer chose the colors and we don't have access to them. The paint color varies so much on computer monitors and in photographs themselves that
choosing a color in this manner is not advisable. In addition, the
light in your space will dictate how the color appears. Our suggestion
is to get a few small paint samples and paint some wooden boards or
cardboard. They can then be moved around the room to really analyze the
color.

Sherwin Williams' Paperwhite SW7105 can look like the trim here. I agree that the bright cream architectural trim looks amazing with the grayer cream of the wall color here. That's what my monitor shows anyway. Kudos to the designer. Nice inspiration. Very convincing as Southern American decor.
