This will look white outside . . what you want is several shades darker ..also be cautious of the brown trim ..there is gray in the stone too .. . i'll come back tomorrow to help . .

Texas Cream is usually a more uniform blond color, but here are a few ideas from Sherwin Williams using your stone.

For the look of muslin . . outdoors test sw antler velvet .. a good neutral

You might also test anew gray and the morris room grey .. they might surprise you with how . .. well .. . neutral they feel out doors. . you are trying to pull a neutral buff tone from the stone . . it will be darker than you think to match it ..

The muslin will be very light almost cream. It would pop the stone. I think it would look great if you went lighter on the trim and garage doors.

Given the very dark roof, the contrast to a lighter color could be pretty! Glad you don't want to go all the way to the dark side of the outside. Love your stone!!! Making it a happy house, not a dreary house, takes effort. Too many people think that dark is classic. If you live where the sun shines 90 percent of the time, it MIGHT be. But every day when one gets home from work, it's nice to drive into the driveway of the lighter color home in the neighborhood, not the dreariest..
