How to change the foreground color in svg to png conversion?

Question

I'm converting fontawesome 5 svg files to png using batik-rasterizer:

java -jar batik-rasterizer-1.10.jar -scriptSecurityOff "svg/" -d "output/" -m image/png -w 16 -h 16

How do I change the foreground color of the resulting icons?

EDIT:

According to the documentation, it's possible to change the background color:

-bg alpha . red . green . blue : specifies the background fill color as an ARGB quadruple, where each component is an integer in the range 0—255,

But there is no parameter for the foreground.

I found a solutions, in the batik rasterizer documentation I found the cssUser argument:

-cssUser file|uri : specifies the CSS user stylesheet to use in addition to any other referenced or embedded stylesheets,

With the following argument a CSS can be added to the conversion:

-cssUser convert.css

Here the css which makes the icons color red:

* {
    fill: #ff0000;
}

Here the complete call:

java -jar batik-rasterizer-1.10.jar -scriptSecurityOff "svg/" -d "output/" -m image/png -w 16 -h 16 -cssUser convert.css
