Find {{ product.title }} and replace it with below code:

    {{ product.title }} 
    <span class="product-color-name" id="product-color-name-{{ section.id }}">
        {%- if product.selected_or_first_available_variant.options.size > 0 -%}

        margin-left: 5px;
        display: none; /* Hidden by default, shown when color exists */

    .product-color-name:not(:empty) {
        display: inline;
    }

    // Simple color name handler - add this to your theme
    (function() {
        "use strict";

            if (!colorDisplay) {
                colorDisplay = document.querySelector('.product-color-name');
                if (!colorDisplay) return;
            }
            
            // Get the color name from the variant
            // Option2 is typically the color variant
            let colorName = '';
            if (variant && variant.option2) {
                colorName = variant.option2;
            }
            
            if (colorName && colorName.trim() !== '') {
                currentColor = colorName.trim();
                colorDisplay.textContent = ` - ${currentColor}`;
                colorDisplay.style.display = 'inline';

            const variant = e.detail?.variant;
            if (variant) {
                updateColorName(variant);
            }
        });

            const variantIdInput = document.querySelector('.product-variant-id');
            if (variantIdInput && variantIdInput.value) {
                const productData = document.querySelector('[data-product]');
                if (productData) {
                    try {
                        const data = JSON.parse(productData.textContent);
                        const variant = data.variants.find(v => v.id == variantIdInput.value);
                        if (variant) {
                            updateColorName(variant);
                        }
