I had to google Tuscan Red. But I don’t think any tan or gold paints will look good with it.
Use an image like this: http://images.easyart.com/i/prints/rw/lg/2/8/Hans-Paus-Tuscan-Red-IV-28140.jpg for reference. Any of those golds, oranges and yellows would work really well with Tuscan Red.
Yes, as highlights, but I wouldn’t want to overdo it.
