Coloring Shapes in SVG
SVG attributes that define how to paint or color can use the values in the following table. If it's a paint-type attribute then you can use color values and the two "non-color" values.
The difference between a paint and color in SVG is simply that paints can use the non-color values. Attributes needing a color can only use a value in 'List 2'. In general, attributes needing a color end in '-color'.
