How do you add a custom input?

I am trying to open the color picker on this input.
<button
    class="toolbar-button inline-flex w-full text-center items-center px-1 py-1 text-gray-500 rounded cursor-pointer hover:text-gray-900 hover:bg-gray-100 dark:text-gray-400 dark:hover:text-white dark:hover:bg-gray-600">
    <svg width="16px" height="16px" viewBox="0 0 16 16" style="margin-bottom: -2px;">
        <g stroke="none" stroke-width="1" fill="none" fill-rule="evenodd">
            <rect stroke="#FADB14" stroke-width="0.5" fill="#FADB14" x="2" y="12.75" width="12" height="1.5" rx="0.125">
            </rect>
            <g transform="translate(2.781250, 1.375000)" fill-rule="nonzero">
                <path fill="#595959"
