You can use CSS to change price color, the class of price is .woocommerce-Price-amount , inject a html section in a hook.

If it is single product page you can use woocommerce_before_single_product hook.

add_action( 'woocommerce_before_single_product', 'price_red_if_not_logged_in', 10 );

function price_red_if_not_logged_in( $wc_print_notices, $int){
if ( ! is_user_logged_in() ) {
?>
<style>
.woocommerce-Price-amount {
    color: red;
}
</style>
<?php
}
}
