Hi @jz9520,
Thanks for sharing more information about your issue. I have tested your content structure to reproduce the error, but I’m getting the right color on the AMP version in my tests. The only difference is that I’m not using the Genesis theme.
My block tree is: Cover Block > Columns > Column > Buttons > Button (with a link and custom colors)
Could you copy the Cover block to check if I’m missing something? On the cover block select, you can click at three dotes and copy the blocks code at the settings bar.
Remember to mark the content as code, for example:
<!-- wp:cover {"customOverlayColor":"#168eff","align":"center"} -->
<div class="wp-block-cover aligncenter"><span aria-hidden="true" class="has-background-dim-100 wp-block-cover__gradient-background has-background-dim" style="background-color:#168eff"></span><div class="wp-block-cover__inner-container"><!-- wp:columns -->
<div class="wp-block-columns"><!-- wp:column {"width":"12%"} -->
<div class="wp-block-column" style="flex-basis:12%"></div>
<!-- /wp:column -->
<!-- wp:column {"verticalAlignment":"center"} -->
<div class="wp-block-column is-vertically-aligned-center"><!-- wp:paragraph {"align":"left","placeholder":"Write title…","style":{"typography":{"fontSize":"58px"},"color":{"text":"#fffffa"}}} -->
<p class="has-text-align-left has-text-color" style="color:#fffffa;font-size:58px">Let Me fight to get your a fair Settlement</p>
<!-- /wp:paragraph -->
<!-- wp:buttons -->
<div class="wp-block-buttons"><!-- wp:button {"textColor":"black","style":{"color":{"background":"#ffff00"},"border":{"radius":"3px"}},"className":"is-style-fill"} -->
<div class="wp-block-button is-style-fill"><a class="wp-block-button__link has-black-color has-text-color has-background" href="#" style="border-radius:3px;background-color:#ffff00" target="_blank" rel="noreferrer noopener">find out for free if I can represent you </a></div>
<!-- /wp:button --></div>
<!-- /wp:buttons --></div>
<!-- /wp:column --></div>
<!-- /wp:columns -->
</div></div>
<!-- /wp:cover -->
