bootstrap 5.3 trying to change dropdown menu selecting color to fit my theme

.form-select.square {
  background-color: map-get($theme-colors, "dark");    // normal bg
  color: map-get($theme-colors, "light");              // normal text
  border-color: map-get($theme-colors, "secondary");   // border color
  border-radius: 0;                                     // square corners (optional)

  &:focus {
    background-color: map-get($theme-colors, "dark");   // keep bg same on focus
    color: map-get($theme-colors, "light");             // keep text same on focus
    border-color: map-get($theme-colors, "primary");    // highlight border on focus
    box-shadow: 0 0 0 0.25rem rgba(
      red(map-get($theme-colors, "primary")),
      green(map-get($theme-colors, "primary")),
      blue(map-get($theme-colors, "primary")),
