Are you able to post a picture as your room is now? What color is your furniture? There are a lot of different whites. What style is your room? If you want to discover that, put in top search box different styles (one at a time), such as traditional, transitional, casual, modern, eclectic, boho, etc. Do you have an inspiration item, such as a favorite piece of fabric, wall decor, or accessory? https://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/family/white-pastel

Hi, right now it's a mustardy color. It has a west and north exposure, so I read that I might want to stay away from whites that have too much gray in them as it could make the room dreary in the am. And yellowish tinges aren't supposed to be good either?
