Change color on button and headline on specific image with text

[Aankl]

Hi all

I have an image with text, where the background is made black, the picture is black -> Therefore the text shall be white.
I managed to change the background color as well as making the tex white.

What I am missing is only to change the color of the action button (text and border) and the headline.

This is the script so far:

#shopify-section-1591167956603 .eight.columns.medium-down--one-half.text-column:last-child .border-style--none.text-align--center {

    background: #000000;

  color: white;

}
