An e-commerce method involves on-line viewing of a first article through a
linking node for virtual merging on another structure. A particular
application of the invention is directed to on-line apparel shopping
involving a color matching scheme using color codes provided with images
to be merged. For example, on-line viewing of one article, such as
clothing, on another structure, includes creating an item from image-data
corresponding to a colored article selected by an on-line viewer from an
on-line viewer site with an image of a colored structure selected by the
on-line viewer, and indicating whether the colored article and the
colored structure satisfy a color-matching criterion.
