Describe your issue

Tailwind config

/** @type {import('tailwindcss').Config} */
export default {
  theme: {
    extend: {
      colors: {
                                         ⬇⬇⬇⬇⬇⬇⬇⬇                     ⬇⬇⬇⬇⬇⬇⬇⬇
        primary: 'light-dark(rgb(0 0 0 / <alpha-value>), rgb(255 255 255 / <alpha-value>))',
      }
    },
  },
}

CSS

                              ⬇⬇                     ⬇⬇⬇⬇⬇⬇⬇⬇
color: light-dark(rgb(0 0 0 / 0.5), rgb(255 255 255 / <alpha-value>));

When adding a color to a Tailwind setting with more than one use of <alpha-value> in a single value, only the first occurrence of <alpha-value> is recognized.
