not to be a bitch, but im not sure this falls under the category of what we call hueshifting, i think of that as being using different hues in different areas of an object that blend to create a believeable color and texture, for example, using sienna, sage, lavender, and beige to create a freckled face where this is more like using using colors to make......well, those same colors. its very cool photos, but im not really sure of the relevence?
