Not sure if you have coding knowledge. But something like this should work in the basis. You can add the shortcode to your loop layout in Divi:

Add to functions.php

// Add shortcode to display product variations in loop layout
function display_product_variations( $atts ) {
    global $product;
    $output = '';
    // Check if product has variations
    if ( $product->is_type( 'variable' ) ) {
        // Get available variations
        $variations = $product->get_available_variations();
        // Loop through variations and display each color attribute
        foreach ( $variations as $variation ) {
            $output .= '<span class="product-variation">';
            $output .= $variation['attributes']['attribute_pa_color'];
            $output .= '</span>';
        }
    }
    return $output;
}
add_shortcode( 'display_variations', 'display_product_variations' );
