Changing NuxtUI Colours Is Not Working

//app.config.ts
export default defineAppConfig({
    ui: {
        primary: "sky", // Main CTAs, active navigation, brand elements
        secondary: "orange", // Secondary buttons, alternative actions, complementary UI
        success: "emerald", // Success messages, completed states, positive confirmations
        info: "blue", // Info alerts, tooltips, help text, neutral notifications
        warning: "amber", // Warning messages, pending states, attention-needed items
        error: "rose", // Error messages, validation errors, destructive actions
        neutral: "slate", // Text, borders, backgrounds, disabled states
    },
});
