Main category color

Hi there,

this theme has standard categories, such as action, rpg, etc. and each category is assigned with a color. Once a post is assigned to a category, it takes over the color of the category. But how do I choose, which color it takes, if I have 2 or more categories?

In my case, I have games that have the category ACTION and RPG, but it always takes the colour of ACTION, while I wish to have the color of RPG (since it is more accurately described as a RPG, not action game). I tried setting the categories as a primary, but didn’t work for me for some reason.

How do I do that?

Thanks,
Ray
