I hope it is possible. Need to dynamically change less variable for using dark theme. The code is below:

@theme: dark;

@colors: {
  primary-violet-light: #608cef;
  primary-violet-dark: #031d58;
}

@primary-violet: @colors[primary-violet-@{theme}]; // have to be #031d58

But even it doesn't work. The error is in the last row.

"primary-violet-@{theme}" have to be primary-violet-dark but it doesnt.

Didnt find solution in another topics, so if somebody have a solution for this I would be grateful for help! Next step is to change @theme variable from app. I use Angular 12.
