How can i that colorful text to show and hide

Solution

You need to check your request variable that represents the 'color name' field, after submiting the form, and render or not the element, like you're already doing with $is_doublename

The code will be something like this:

<?php if (!$is_colorname) : ?>
    // Html code to print the name
<?php endif ?>;
