I just painted my bedroom and master bath SW Alabaster with SW High Reflective White trim and doors. I LOVE the look, both colors work beautifully together. Depending on the time of day (morning sun) it looks white without being too stark white, as the day progresses it warms up turning into a vanilla cream in the evenings. My bedroom is west facing with more windows and a small south window. My master bath is west facing. The High Reflective White stays pretty true to color at all times. Unfortunately they were not able to do the cabinets in HRW as the paint I used on the cabinets could not be mixed in that color. HRW is a color that is funny at Sherwin Williams and kinda' tricky and definitely takes more coats to cover. I used Emerald paint in Alabaster on ceilings, walls, and cabinets in different finishes and Super Paint in Semi Gloss in HRW for trim and doors. I was nervous about using Alabaster on the cabinets in the bathroom but it worked perfectly. I will say, for those that are using a white on walls that is not as warm as Alabaster/White Dove, or more cooler grays (think grays that aren't greige) the Alabaster or White Dove warm soft whites are going to go yellow/cream. I would recommend going with Pure White for cabinets and trim. It is still a soft white without the creaminess of Alabaster. High Reflective White is also a good white it's not as soft as Pure White but still not so white that it looks cheap, but again HRW is hard to cover and cannot be mixed in many sheens and paints. I decided not to go with Pure White with my Alabaster walls because my husband wanted more of a contrast with the doors and trim, I wanted to use Alabaster on everything, but made a compromise with my husband, and went with HRW. I am not at all disappointed with the look. I know I spent countless hours agonizing over the choices and hopefully this will help others that are in the same position.

Why not do the ceiling like the walls or cut 25% don’t make things any more complicated than needed.

SW High Reflective White will look more neutral, crisp and whiter next to SW Alabaster. SW Extra White has a little less contrast with SW Alabaster, so the combination will appear softer. So it depends for which look you are after. The two whites need to have a perceivable difference in Chroma (colourfulness) in order that one doesn’t make the other appear dirty.

@Ac Lb Hi! I went with SW Alabaster on walls and SW extra white in semi gloss on the trim and uppers. Will post a picture. One thing, use the SW Emerald if going with alabaster - the contractor did ProMar 200 and it was awful. They upgraded to Emerald and it made a HUGE difference, the walls look entirely different.
