You can force the color mode at the page level by setting the colorMode property using definePageMeta:
<template>
<h1>This page is forced with light mode</h1>
</template>
<script setup>
definePageMeta({
colorMode: 'light',
})
</script>
This feature is perfect for implementing dark mode to a website incrementally by setting the not-ready pages to colorMode: 'light'.
$colorMode.forced value.
