The Theme Editor allows you to choose your own colors for your website. You can use the color picker to find a color for any part of your site, whether the site background, fonts, or anything else.
If you already know the hexadecimal code (that is, the six-digit code for each color variant) of a color that you want to use, you can paste the code into the field below the color picker, as shown below:
To obtain the hexadecimal code of a color, use a color picker like Color Cop or upload an image to ImageColorPicker.com and pick out particular hex codes from it. There are a number of other color pickers out there as well.
When you're finished editing your site theme, click the button to save (the disk icon), then close the Theme Editor by clicking the X button.
