Our Benjamin Moore paint store has a woman who will come to your house and help pick wall colors and help with the flow from one room to another, as long as you purchase the paint from them. You really need someone to be there in person to see how the house flows and especially how the light varies from room to room. Trim/door/window paint color kept the same also helps the flow and even “white” trim can be tricky depending on the mix of cool vs. warm tones - especially with neutrals and you mentioned gray.. The two Benj. Moore trim paints recommended to me were Simply White or Chantilly Lace which work with warm or cool neutral tones.

That is not what I am saying, exactly. A north facing room, from the GET go, may require a much warmer white than you'd have in your marble bath. Yes, all rooms change with the light. But some may begin ( One Paint ) as warmer, cooler , dingier to start. The search for ONE that makes you happy everywhere in every room can be quite a challenge, unless all your rooms are flooded with light. Or.......you accept that some rooms ( your results ) will appeal to you more than others, with just one white, everywhere. Also be aware that white is BEST with lots of light, and even better when used somewhat liberally in fabrics. Too much going on in a room, a lot of pattern or color, or dark furnishings ...(especially a case with leather sofas, large and brown...........) can make for a disjointed and very nervous space.

L L - Is it easy to wipe clean? ..... I am so curious about Superpaint Velvet Vs Satin(Eg Shell).. anyone know what the major difference is or have suggestion about which would be better. We are using High reflective white throughout.

Yes, certainly, though since the light will be different in different rooms (due to number/size of windows and orientation) the color might look different from room to room. You occasionally see posts where the homeowner used the gray or greige or beige they loved in their living room that looks pink or purple or yellow or green or baby blue in their back bedroom. Also, the same color may look great at one time of day but not-so-great at a different time due to the changing light. Always test the color(s) you are thinking about using in the actual space(s). A lot of people find it helpful to paint a large foam board that they can move from one wall to another or from one room to another.
