The example you posted is for the button group. We already support setting each individual button color for button groups. See the docs https://blazorise.com/docs/components/button

For RadioGroup, it is a different story because they are a "hacked" version of buttons that are applied to the label TAG. While it would work initially, it would not be ideal. For example, border colors would be different for buttons.

We don't have plans to add this feature at the moment.

I don't understand what you mean by the border colors. I was able to modify the classes in the DOM to make the demo show what I want.

But I'll see what I can cobble together with the button group instead

By border colors, I meant all of the styles. For hover, active, disabled states. They could leak into neighboring buttons and could look weird. But, I could be wrong. So, I need to try it and see how it goes.
