Good pairing Oyster White

with Revere Pewter by Benjamin Moore.

Or Gray Mist is close to Oyster White

and Revere Pewter BM as well.

At least use paint appropriate for masonry, not regular house paint. I see Romabio recommended here on this forum often.

Well... it already is a cream brick. You might start with a thorough cleaning of the brick if that hasnt been done in many decades - that would have to be done anyway prior to changing the color, and you might find the current color considerably brightened and improved. I know I was surprised how much dirt and algae came out of my 100 yr concrete brick. Otherwise as above poster indicated, you would need to use a breathable mineral paint such as Romabio or - Keim, Beeck and LImeworks are other US sources. These chemically bond to the masonry vs an acrylic or latex film that sits on the surface andcan lead to damage of brick or mold issues in the house if water vapor is trapped behind the paint film.
