Issue description

The addition of the Brand Center gives users the ability to have specific secondary colors in their theme. In SPFx, we get access to these based on the section background.

In the first theme, Novia Dark with Yellow - the secondary colors are:

• black
• red
• white

The question or request is how can I access the secondary colors outside of dynamic sections. The expectation that users can now choose these colors in extensions or web parts regardless of the section background.

Is there a way to expose or access brand center secondary colors?

I know there is the themeVariant and the experimental 'schemes' object - but that only gets us neutral, soft, strong (which are just variants on the primary theme color)

Let me know if I am overlooking something - Thanks!
