You can Google painted ladies, painted Victorians and look at houses where they have picked out the details in 3rd, 4th and 5th paint colors. The neutral tones you have now would be easy to add to. Navy, deep red, dark blue-green, lavendar. I would find some examples you like that have more than two colors, buy some sample pots of paint and try it out. You have made a significant change; be careful to give yourself time enought to let it really sink in. You may decide that you like it after all. Did you paint your front door and contrasting color? That may me the first thing to try.

It's an act of faith to jump in and use paint traditional to period architecture or decorating. The last time the exterior of our home was redone, it had been seventy five years previous. When they gave us the choice of shades they could incorporate into the mix, and the dh and I were brainstorming, the sales consultant poked fun of a yellow sample, saying that it would make a huge old house look like a giant stick of butter. I told her to go for it, and we've never regretted it since.

The beauty of most Victorian homes are the lines and detail work. If you must change paints, I'll bet just going to a crisp and darker detail to accentuate those things over the pewter base would go a long way toward making it more what you expected. Yes, and even simply painting a door can make a big difference. I just sold a hundred year old town house. Yes, it was a pewter and it just didn't zing. I painted the door wine red. It helped A LOT.
