Thank you very much! It looks great. I've already connected everything, and the objects are basically ready. Thanks for the xdb portrait; it sped up the process a bit.
I'll try to figure out the files; maybe I can recolor something myself if needed.
For now, just a "plus to your karma".
Here's my "original" texture in pdn format (I don't know if you can open it in Photoshop; this format is used by the Paint.NET program). The trick is in the layers: the first layer is the yellow stone of the monument, and the second layer is the colored stone, which you can safely recolor without damaging the first layer.
