Help with Custom CSS (Changing font color to white)

Skyswipe

I've scrounged around the forums and it seems I'm not the only one. Using the dark theme, many users want to use a white color font for the header and also for buttons for better contrast and readability. I did try to experiment with inspect element but it doesn't always work. I managed to change the font color to white for the header only using this:

@header-control-color: #fff;

Now I'm stuck on on how to change the font color inside buttons, particularly this:

Any help is appreciated.

.Button--primary {
color: #fff;
background: #e7672e;
}
