I've got some marshalite ash decorative bricks for a garden wall, see
formatting link
The are basically stone effect, grey, but with some larger brown/yellow flecks (i.e. made of cement with some larger grit sand in it). Can anyone suggest a good mortar mix that will bring out the yellow tones in the bricks? I've seen the wall done with a brown stained mortar but it looks terrible. Basically, I don't want it to look like "cement" if you get the idea. Mix needs to be strong enough for a 4" thick wall with 8" piers every metre, about 6 courses high. Thanks, Simon.
