As per Dummy:
Think I would check at a local concrete mixing plant that produdes paver blocks etx. They should have the dye, don't even think of green, get some mortar sand, some motor cement and also some portland cement. The portland cement will help add strength. Mix at 3/1 sand to mortar and add a little extra portland and just enough water to make it workable. For the small amouts used economics is not really a factor so heavy on mortar and cement will not hurt. Just get it to a nice sticky stage so that if you slap it on a vertical wall it sticks.
If you want portland cement and lime properly mixed will also give the right consitency.
A good paint mixer and electric drill work well for mixing small quanities.
Sand blasting the exterior of the product may help for desired look.
The bagged mixes have never appealed to me.
