Selectors:
[color]
All fill
and stroke
attributes
[fill]|[stroke]
All fill
or stroke
attributes
tagName[fill]|tagName[stroke]
fill
or stroke
tag attributes with name tagName
.className[fill]|.className[stroke]
fill
or stroke
tag attributes with class className
colorGroupN
All colors in SVG are grouped in color groups. N - group index, starts from 0 (from the top of SVG document)
#identifier[fill]|#identifier[stroke]
fill
or stroke
tag attributes with id identifier
