Hello, I am not familiar with the term " Spanish Lace" however, if you add dry pigments or Universal Tint to you JC you will get a beautiful Tuscan Color. I would suggest to a Yellow Ochre and a bit of Rwa Umber. Mix thoroughly and apply in skip trowel fashion. Remember that the color will get lighter once try. I suggest to make a few samples and let them dry before you attempt an application.
Hope that helps
Warm regards,
