I am following the following guide to define my custom node appearance:
However I can see that the background color is defined by a "color" property that is a muted palette of colors. Is there a possibility to set more parameteres to that, i.e., a way to configure a css for that specific custome node or set it within the html file directly? When I click "Inspect" on my custom button within the palette, I can see:
background-color: rgb(70, 143, 135);
However I can't find where it's configured.
Thank you for your answers.
