1. A method of operation in an automated Web portal generation system to generate sets of customizations of Web portal templates, the method comprising: parsing, by at least one component of the automated Web portal generation system, a number of Webpages of a first Website, represented by a domain or Universal Resource Locator (URL), from which a Web portal template to be customized is to be accessed; producing an entity feature set for the first Website based on a result of the parsing; processing the entity feature set for the first Website via a classifier executed by at least one component of the automated Web portal generation system to produce a set of data that represents, for each of a plurality of entities, a respective probability of the entity belonging to a respective one of a plurality of classes; performing color matching on the set of data produced via the classifier to generate a number of proposed color combinations for a proposed customization of the Web portal template, wherein performing color matching to generate a number of proposed color combinations includes identifying candidate background colors by evaluating contrast between colors of each pair of a plurality of pairs of colors in a device-independent color space; ranking pairs of color combinations based at least in part on the probabilities from the processing via the classifier; returning the ranking as a collection of results for user evaluation; and identifying one of the proposed color combinations for a proposed customization of the Web portal template.
