Change the predefined colors for the module-styles

Hello!
I would like to change the predefinded colors for module-styles. As I don't find any setting for this in the customizer i have looked for this settings via 'Firebug' and found them in the CSS-File 'theme.css'
Changing the color-values, saving, uploading to the source directory and refreshing the page has no effect; the colors are the same as original predefined.

So, what can i do to change the values?

Thanks,
Frank

Hi Frank,
the module styles, box, primary and secondary can be changed at the Customizer > Advanced >Panel

Dont edit the theme.css becasue this file will be overwritten if you hit the button "compile less".
You can use the Customizer and also add your own CSS by creating a custom.css file inside the /css folder for the related style. That way your CSS won't be overwritten when you save changes in the Customizer.

Thanx, now it works fine

BTW: LESS stands for what?

Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.
