New variables are available in Store Editor which will allow you to customize the color scheme on all Store Editor pages, including Variables, Edit All, Controls, and Config. You'll need to manually add these variables (of type color) before you can use them; once added, you can make changes to them in the Config page.
To make the changes, click choose a color to open the color palette or manually type the decimal color code in the text field. Note: You can use hexadecimal values for color fields if you prefer--just visit the Controls page find the Color Code Input pull-down menu, and select Hex.
