In this section, we’re going to show you how to change your WordPress theme colors the manual way. To do this, you’ll want to use a ‘child theme’, so you don’t lose any of the changes you make when the ‘parent’ theme is updated.
What’s more, setting up a child theme is almost always a smart idea if you plan on making any custom changes to your site’s framework. Let’s talk about how to get the job done.
Step 2: Log In to WordPress and Open the Customizer
Before you can change your WordPress theme colors, you’ll need to log in to your dashboard. Once there, navigate to the Appearance > Editor tab:
There, you’ll find a simple text editor that enables you to alter your child theme’s files. Keep in mind that you can also do this using FTP and your favorite text editor, but the results will be the same either way.

In either case, you’ll need to use Cascading Style Sheets (CSS) to alter your theme’s colors. That’s where our final step comes in.
Step 3: Change Your WordPress Theme Colors
if you want to change your theme’s background color, you can add a CSS snippet like this to your child theme :
EXAMPLE : background-color:black;
Press the save button. and its done.
