We are building a house that has beige siding with stone accents that are tans, browns, yellows. The house has a black door and black shutters.

For our front porch, we are doing stamped concrete, and have been told we need to pick a base color and a color for the powder they put on top so that the mold does not stick to the concrete.

In order to tie in the black doors with the brown/tan elements, we thought about doing a gray base, with tan/brown powder release. Does anyone have any experience with stamped concrete colors and how they work with each other. I.e., do we need to pick two gray colors or can we mix and match.

Any help would be greatly appreciated!!
