There are lots of spotted horses portrayed that are probably dappled but some of them could be "appaloosa" coloring. I have included several of the spotted ones less likely to be dapples. These pictures are in rough order by date. Fashions in color are obvious if you go looking at the horses in paintings. At some points, greys are very popular. It seems that in the 17th c. "paints" were popular.
