Hi there!
The color is coming from the preset.
However, you can use the following code in your custom CSS(please use your own color/color code instead):
.educon-latest-news-wrap .educon-latest-news .sppb-addon-title{
background: #3fb553;
}
.home-callto-action2::before{
background: rgb(181 101 63 / 90%);
}
Note: Path towards custom CSS:
Extensions>Templates>Styles>
Click on your current default template name then choose Template Options.
Then find custom CSS within the custom code.
