@theme-color: var(--theme-color, #5582F3); @hsv-h: hsvhue(@theme-color);

it has the error error evaluating function hsvhue: Argument cannot be evaluated to a color

This is not possible. The value of the CSS variable --theme-color is only known by the browser at runtime. Less will only see the text input "var(--theme-color, #5582F3)" at compile time and can't apply a color function to it.
