Before you start changing the colors to your site, decide on the color scheme you want for the Header, footer, page background, and fonts. Make sure the colors complement each other. Keep in mind that the colors will vary based on the screen that is rendering it. Generally a light background on the page with a dark font is less tiring on the user’s eyes. A splash of color in areas where the user does not need to spend a lot of time focusing can enhance the overall appearance and still maintain a positive experience for the reader.
The colors are stored in files or code called CSS (Cascading Style Sheets) and the main files should not be changed. Any time the theme is updated, all the CSS code is changed as well. WordPress has created a feature called child themes which will preserve your modifications even when the theme author puts out another theme update.
The rest of the pages in this section will describe where to make changes to the colors on the web site. Some are found in global settings, but some need to be changed modifying the child CSS file.
