Patti's Blue House

It's been a very long time since I did any art, let alone an oil. Life has been really messing up my plans. But I was able to get away one evening a week ago and headed up to my favaorite place in the world - the little park north of the Braddocks Bay Marina. Again I struggled with values and mixing the correct hue in oils. The scene is fairly accurate, though, and that's a good thing. But I can't seem to get the values dark enough and am not sure how to get those really dark values without resorting to using black, which is something I don't want to do. I want my dark values to sing with color, not black. Size 6x8
