Gutters and downspouts are not decorative elements.

Gutters should match the roof or soffit/fascia colors so they "disappear".

Downspouts should match the house siding color so they also "disappear".

Yes, your gutters and downspouts will be a different color, but they will each blend into the surface that they are attached to.

Your roof has a red undertone and Urbane Bronze has a green undertone, esp with light bouncing off the foliage. Could be tricky.

I like the idea of Charcoal and that Iron Ore is nice.

Since the windows are dark brown, keep the trim the same color as it is now? It looks good with the roof.

The deck could be a natural neutral wood stain like Walnut to tie in the roof. The paint is Cheating Heart on this example from brickandbatten--Blue undertone.

Paint companies have a Visualizer online you can upload your house photo and "paint" it using their colors. Google the exterior undertone of any colors you look at.

If your siding is wood, then you'll be using a solid wood stain and NOT PAINT. Paint peels off. Stain adheres to the wood better.

IMO a gray stain would bring out the best colors in the stone.
