Specialist waterproof colured pointing mortars are used to complete the effect.

When rebuilding is finished, mix pointing mortar and apply to the raked-out joints.

(Pointing mortar, with its higher cement content, is more likely to crack than bedding mortar.

The joint profile would be as rectangular as possible as the new pointing mortar should be allowed ample opportunity to bond with the masonry unit.

To rebuild a mortared stone wall, use the same techniques but use bedding mortar before you set the stones in place and then pointing mortar after the wall has been restored to full height.

In other cases, especially where the mortar is pigmented, the bedding mortar is removed from the joint before it hardens (usually a depth that averages about one inch), and then pointing mortar is applied in the void and shaped with a finish profile.
