@PPF. yes that is my brick.

Take a brick to the paint store and have it color matched that is IMO the only way . Wher eis this going ?

The word is "blend"

Take a few sample bricks to a Benjamin Moore. You can't "match" an opaque paint to a totally different texture/material which has multiple tones of white, and even a hint of pink.

Even then, a test directly on the house, at your site is necessary to be foolproof result.
