is there a possibility to change the colors via HEX format e.g. #fff0000

"xpbar": "green", -> "xpbar": "#00ff00",

we would like to adjust the colors of the bars to Rust so that they are not so bright.

it should accept HEX if you manually set it in the config file

It only worked via RGBA e.g. for red instead of #ff0000 this 1.000 0.000 0.000 1.00, but thanks.
