These statements are very similar to the codepaths above for fill and stroke. Is
there an easy way to extract this logic out into a function? This is just a
suggestion.

+            parsedValue = SVGColor::createFromColor(RenderTheme::defaultTheme()->systemColor(id));
+        else if ((id >= CSSValueAqua && id <= CSSValueTransparent) ||
+                (id >= CSSValueAliceblue && id <= CSSValueYellowgreen) || id == CSSValueGrey)
             parsedValue = SVGColor::createFromString(value->string);
         else if (id == CSSValueCurrentcolor)
             parsedValue = SVGColor::createCurrentColor();
