I found another site that gave me the general color selections. I was missing orange. Apparently the "Tuscan" look can be anything from deep red to orange to splashes of green.

I also suspect I need a glaze because the sponging effect dries too quickly and I end up with a speckled look instead of a sweeping merge of color.

I think if you get one of those color swatches in the color you want and get the lightest tone at the tip of the swatch, the middle tone, and the one at the bottom you will get the effect you are looking for.

she used a cloth and not a sponge and I thought the red was a crazy idea. However, the walls became more of a goldish orange and it looks like stucco. You can't really call it orange or yellow so it's hard to explain. I think the red had more brown in it and that toned everything down. It changes slightly with the natural daylight.

I have more of a technical mind. If I get the right technique down, however, I'm convinced that it will be foolproof.
