How do I change my ProductItem-details-excerpt color?

Site URL: https://www.robbymillerphotography.com/shop/p/fire-in-the-sky-over-hood-river

My product detail pages ' product descriptions seem to have an odd span that is hard-coded wtih a gray color that I can't figure out how to change.  Here's the excerpt:

<div class="ProductItem-details-excerpt" data-content-field="excerpt">
        <p class=""><span style="color: rgb(38, 38, 38)"> A pontoon plane rests on a dock at the Hood River Marina as the sunset over Underwood Mountain sets the sky ablaze.</span></p><p class=""><em><br></em>More about <a href="/pring-options" target="_blank">print options.</a><em><br><br></em>Ships within 2-4 days</p>
      </div>

Thanks for your help all!  I really appreciate it!

Description, you copied from other source or you typed it?

Add to Design > Custom CSS

.ProductItem-details-excerpt p * {
    color: white !important;
}

That did the trick.  And yeah, I copy/pasted the text from another editor and I didn't even think that there was markup coming along with that.  I'll try to delete and re-rewrite the text to see if that changes things.  Otherwise, the Custom CSS approach was spot-on.  Thank you very much!
