Hi,

Thank you for your question. Here are possible trim colors for the Match of Sherwin Williams Repose Gray. You will want to sample the colors together, as they can vary due to lighting any space.

Match of Sherwin Williams Marshmallow SW7001 http://www.myperfectcolor.com/en/color/26908_Sherwin-Williams-SW7001-Marshmallow

Match of Sherwin Williams Ice Cube SW6252 http://www.myperfectcolor.com/en/color/27101_Sherwin-Williams-SW6252-Ice-Cube

Match of Sherwin Williams Futon SW7101 http://www.myperfectcolor.com/en/color/73736_Sherwin-Williams-SW7101-Futon

You will really want to experiment with the trim color to get the right combination, as gray can be warm or cool.

Thank you again,
Diana

Hello,

Thank you for your question. I'm unable to give you formulation advice on already mixed paint, as there are so many variables when not seeing it in person. Perhaps someone with knowledge on what, if anything, can be done to reduce the yellow, they can add a comment here, too.

Thank you,
Diana
