is_category archives

Hello

I’m trying to display four diferent categories in four diferent archives, doing for diferent archives. I’m using is_category but nothing is displayed.

<div id="primary" class="content-area">
	<main>

		<?php

			get_template_part("template-parts/content","page");

			$args = array( 'post_type' =>portfolio, );
			$query = new WP_Query( $args ); 

			if ( $query->have_posts()) : while ( $query->have_posts() ) : $query->the_post();

				if(is_category("imatge-coorporativa")):

				$image = get_field('imagen');

					if( !empty($image) ): ?>
						<article class="article-portfolio">
							<a href="<?php the_permalink(); ?>">
								<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
							</a>
						</article>
				<?php endif;
				endif;
			 endwhile;
			endif; ?>

	</main>
</div>
