wp cover应用，懂的来💻💻
我现在希望 wp cover 适用于整个主体，而不仅仅是一个区块。它不允许我指定实际颜色的十六进制值。有没有办法可以指定封面颜色的十六进制值
<!-- wp:cover {"overlayColor":"contrast","isUserOverlayColor":true,"layout":{"type":"constrained"}} -->
<div class="wp-block-cover"><span aria-hidden="true" class="wp-block-cover__background has-contrast-background-color has-background-dim-100 has-background-dim"></span><div class="wp-block-cover__inner-container"><!-- wp:paragraph {"align":"center","placeholder":"Write title…","fontSize":"large"} -->
<p class="has-text-align-center has-large-font-size"></p>
<!-- /wp:paragraph --></div></div>
<!-- /wp:cover -->
