I do use blended colors and usually whole stitches. With my own charts, there's enough to make it easier. (Green and purple = blue-gray!)
I did one with half stitches, though - a view of the Grand canyon, in the "National Park Needlework" series, and it's gorgeous. The blended threads are the texture of the ground and the rocks.
