I recently started playing around with the GP child themes (Mantle, Forefront, etc) and noticed that colors, typography, etc were set in the functions file, so I tried to bulk modify all the colors via the functions.php file (change the blues to greens, etc). Color and typography options in the Customizer are limited when not using GPP — which I have, but it is not installed on this particular site. Is there any way to modify Mantle’s colors via its’ functions.php file on a live site — or do the colors, typography and other customizations in functions.php need to be modified before the theme is installed? Seems to me that customizing and color-themeing a site would go a lot faster via functions rather than the Customizer.
