The Goran theme doesn’t have any built-in way to switch from its red color to another color, so your best bet is to make the color changes with CSS. It doesn’t necessarily have to be too complicated, though. Here’s how I’d approach it:
You can use the tips like How to Find Your Theme’s CSS to look up each piece of the theme that’s currently red. For example, when I inspect the header area in Goran I see that the red color is defined here:
.site-header {
background: #b23d3c;
color: #fff;
}
You can search the Goran style.css file to find all the CSS declarations with that #b23d3c red color. Then, you can create custom CSS to replace them with the green color you want, like this:
.site-header {
background: #67b23c;
}
I’d recommend using a custom CSS plugin (like the Custom CSS module in Jetpack) to add that as custom CSS to the theme.
You can keep doing that until you’ve replaced all the red in the theme with the green color you want to use. Please let me know if you have any questions about that. ??
