FeathersUI: simply changing "some colors"?

Hi, I was looking at the custom theme FeathersUI example (https://github.com/feathersui/feathersui-openfl/blob/v1.1.0/samples/custom-theme/src/Main.hx). I was wondering if there is a way (or an already developed theme) to easily change just some properties of all components at runtime, like getting the theme of the default dark mode and just give it some slight color changes.

Nevermind. It was much simpler than I was expecting: just extending the SteelTheme and setting the color parameters easily did the trick!
