It's not the task of the Color module to define HTML or SVG. In hindsight, maybe the specification would have been clearer without those examples... We called the list of color names "SVG color keywords" because we copied them from the SVG specification and because the SVG specification is unambiguous. It doesn't mean that the colors are only allowed in SVG. We could have called them "X11 color names," but there isn't a unique list of X11 color names, as far as I know. Different implementations of the X Window System have slightly different lists. The Color module describes a set of features, but it is not a complete specification by itself. It's supposed to be a module in something else. We hope that every format that uses colors will use as many colors as possible from this module, ideally the complete set. We also hope that everywhere where CSS is used, all the properties and all the colors can be used as well. But we know already that in the CSS Mobile Profile, e.g., the system colors are optional. Nevertheless, there is an implicit assumption that in the most powerful CSS implementations, viz., on desktop computers, the whole module will be supported.
