I have a home that has light grey siding with light brown brick. The brick is not a solid color so I was thinking of dry brushing some light grey onto the brick to make the brick and the grey siding match better. What would be the best way to go about this? Type of paint to use? Any special brushes or tools that might come in handy? This is a 6 year old home so the brick doesn't look aged, it just doesn't match!
