SVG 1.2 Tiny allows this, see the spec[1] (and if you scroll down a bit from there, there's even a complete example of how to use it). In a <solidColor> element you can set the 'solid-color' attribute to whatever color you need using the normal svg syntax for colors, and by giving the <solidColor> element an id you can reference this as a paintserver, just like a gradient, e.g url(#mycolor). Opera 9.5 supports this, if you are looking for something to test in. > In the GeoSym standard, when the various attributes of a feature are > looked up and evaluated to select a final portrayal image, the color > of that image is defined by a specific name; that name has to be used > as is, or else somehow translated from GeoSym into something that SVG > can understand.

It's possible to animate the solid-color attribute, does that solve your problem? > My question, my understanding of the underpinnings of SVG being as > weak as it is, can this color definition method be supported within > SVG itself, or must the colors first be translated into RGB values > externally and fed to SVG? Depends if the colors are defined in svg already or not, see the <color> syntax[2].
