Paint-obsessed!

A bit tired- the tiny terrorist is ill with now diagnosed tonsilitis, so he is sleeping with us at night.

Currently obsessed with paint selection.

1st issue- small house
2nd- different light & orientations

The first 2 bedrooms face west.
The 3rd bedroom faces south and has a small window
The 4th/living area has a small north window on the main wall, and a large glass window/door to the east.

Am very confused- light will vary significantly.  Light from the west is yellow-toned, light from the south is apparently grey and it'll be my dark room, and the living area is a bit of a tunnel.

The non-tinted white is Vivid White
Warm whites are recommended for south facing/dark rooms
Cool whites are recommended for north rooms

Should I paint them all differently?

I want to cover all woodwork frames with white, as I don't consider the wood to be a design feature.

Warm whites- options appear to be Chalk USA, but I really like Fair Bianca 1/2 for when we painted our currently dark home.

Also thinking about painting the wall behind the tv area (a bit horrified at the size mentioned to me)- choices (french grey? taupe ie hog bristle? or chocolate ie Toffee Fingers),  not sure how it will go with a non perfect wall.

Yes, will probably end up calling the Dulux paint consultant.
