I have Soft Chamois in several rooms in my house and sampled Seapearl before choosing Soft Chamois. They are both warm off whites - Seapearl is a little brighter. I chose SC because it's a little more subtle. However, based on what you're showing here they're probably both going to be too warm (yellow) to go with your stone and cabinets. I think you're going to have to lean more gray. Look at Classic Gray, White Wisp or Dove White (not White Dove). If the quartz looks good with the cabinets then choose a white or off white from it. You have to be looking for something that will go with your flooring as well since the wall color will be next to the floor also.
