Following as I am painting my walls Simply White. I am doing Aura matte and wondering if trim should be the same in a semi gloss. My doors will be black.

The same color in matte in fact that is also the finish I would choose for walls.

@HU-969855738 I was terribly busy yesterday and didn't get the opportunity to respond to you. The three colors I picked out when I made my suggestions were very different undertones, but were meant as examples of the depth of color. There are two factors that go into finding the perfect color that are really difficult to do via the internet. One is that color preferences are extremely personal and two, colors have to be looked at as a collection of colors. It must be 25 or 30 years ago when I came home to Pennsylvania for Christmas. Back then, when my mom was still alive, the entire family gathered at her house for Christmas Eve. It was quite the celebration and we all took pains to find the perfect outfit. My sister Betty lived here in Pennsylvania, Susie drove in from New Jersey and I flew in from California. Apparently there was one outstanding velvet pant suit sold across the US that season. My two sisters and I had all bought it. I have ivory skin and dark sable brown hair and dark brown eyes. I bought the deep Christmas Red. Susie has olive skin and golden brown hair and brown eyes. She bought it in deep Emerald Green. Betty has dark blond hair, fair skin and hazel eyes. She bought it in deep Navy Blue. We obviously have very similar taste, but our coloring is not the same and our homes reflect these same differences. We all live in Pennsylvania now, but Betty's home is decorated in a contemporary style and her color palette is soft beige and pastels. Susie has a tudor home with an eclectic mix of Antique and Industrial furnishings with a fall color palette, deep oranges, golds, browns and greens. My home is an MCM home with MCM teak furnishings. I am renovating, but my color palette is being pulled from the colorful slate entry (called Red/Purple/Green slate). Walls have not yet been painted, but here is a picture that shows the entry tile (with drywall dust): I am using a lot of reds, teals and gray purples (my final decor will not include a paint sprayer on the hearth). To know what will work for you we need to understand what your style is and what colors make your heart sing. What are you using with the Super White trim?

You might also look at BM Winds Breath. Can be really nice but it's more of a greige than beige.
