Can bed file show different colors?

[Jasonzzzzzzzzzzzzzz]

I have some bed files like:

chr1 76800 77000 2 0 . 76800 77000 247,104,161
chr1 77000 77200 15 0 . 77000 77200 255,255,255
chr1 77200 78800 7 0 . 77200 78800 191,143,0

and the filed 8 is the RGB of the color.
So, can i use these RGB to show different color in the Jbrowse 2?

Here is an issue thread with a workaround that was suggested by a user

#1734

I tried that config. When the color value is RGB, this configuration has no effect. This configuration only works when using hexadecimal (e.g., #458B74).

and another example,

renderer: {
type: "SvgFeatureRenderer",
color1: "255,250,205" // it cant work
}

renderer: {
type: "SvgFeatureRenderer",
color1: "RGB(255,250,205)" // it can work
}

renderer: {
type: "SvgFeatureRenderer",
color1: "jexl:get(feature,'field8')" //I guess this result should be the first one, so RGB cant work
}

Is there a way to use RGB values, or can I only use the hexadecimal format?
