        $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);

        // Get entity type ID for catalog products
        $entityType = $eavSetup->getEntityTypeId('catalog_product');

        // Check if the attribute exists
        $attribute = $eavSetup->getAttribute($entityType, 'color');
        
        if ($attribute) {
