A tree at my house in Seattle, Washington, USA has these leaves. Can someone tell me what it is?

It looks similar to a Cotinus coggygria, which is a shrub that we call a Smokebush in the UK. But given your location, it could be Cotinus obovatus, known as American smoketree.
See http://dendro.cnre.vt.edu/dendrology/syllabus/factsheet.cfm?ID=415
The leaves will start green and progressively change colour to deep reds in the autumn with sprays of pink-purple flowers in the summer that from a distance look like smoke, hence the name.
Here are some images I have found on the web.

I think this may be a Chokecherry. Prunus virginiana 'Canada Red'
Found this on a Washington nursery website so it would make sense that it would be planted in your region. I am inclined to think it is closer to this species than a smoke bush based off what I can see from the flower in the photograph.
