No response

Description

This is our theme-color generator command, running it twice results in "already exists" even with --force, also --defaults seem to have no effect here.

pnpm ng generate @angular/material:theme-color --force --defaults --directory="/libs/app-theme/vendor/material/" --primary-color="#0641e6" --tertiary-color="#994aff" --neutral-color="#313138" --error-color="#eb5757" --secondary-color="#009096" --neutral-variant-color="#b2b2b8"

Path "/libs/app-theme/vendor/material/_theme-colors.scss" already exist.
