How to change color of search button in wordpress

The appearance of the frontend is determined by the GeneratePress theme you have chosen. The colour for the search button is also in the style.

You should be able to adjust the colour of the button with the following individual CSS:

.wp-block-search__button.has-icon { background-color: #00ad45 }

You should insert this under Appeareance > Customiser > Additional CSS.

If this does not work, it is best to contact the support of your theme: https://www.ads-software.com/support/theme/generatepress/
