Need assistance with CSS classes (i.e. fontColorThemePrimary, fontColorBlueLight, etc.)

[calmkza]

I really do apologize if this is not the correct place to post this question, but I have no idea where else I should look.

I am trying to use one of the templates on several sites while rebranding each with its own color theme. The theme itself isn't an issue. What I'm having a problem with is the use of classes such as fontColorThemePrimary and fontColorBlueLight, which are used on some of the elements in text web parts.

I can't find any resource that documents those classes. All I find are classes like ms-fontColor-blueLight. But the only two that seem to work are the two I mentioned above. Anything else either doesn't change the color or somehow gets removed when rendering the page. I took a guess on one by using fontColorYellow and that worked. But fontColororangeLighter didn't (nor did fontColororangeLight or ms-fontColor-sharedOrange10).

Can someone give a little guidance on further customizing these templates?

Thank you!
