when the tiles are new, will they be stained by the dye in the grout mix?
If so, does the grout need to be closely matched to the tile color,
or is there another solution?

Due to the high porosity of Saltillos, a pre-sealant or use of a grout
release is advisable before grouting. Usually... 'USUALLY'.... with
the proper use of a pre-sealant, there should be no problems with
color bleeding. Brazilian and Spanish tile "can be" (not saying are
always) a bear to work with as far as keeping "uncontaminated" during
construction/installation.
