How to change bold font color for slate theme

[wizo06]

I've implemented the color palette toggle on my site, but I noticed that the slate theme isn't really up to part to my liking. So I decided to edit some variables as suggested by the documentation

[data-md-color-scheme="slate"] {
  ...
}

The bold fonts in the slate theme is not very distinct from regular font, so I wanted to change the font color specifically for bold fonts. I looked through the file containing color definitions for a list of all CSS varialbes, and realized that there is no variable for bold fonts. My solution was to add these lines

[data-md-color-scheme="slate"] {
  ...
}
strong, .md-nav__title, h2, h3, h4 {
  color: rgba(255, 255, 255, 0.87);
}

What's the problem?
It affects the font color for bold fonts in BOTH slate and default(light) theme.

My question
Is there a way to change the bold font color only for slate theme?

I figured it out. I just had to use css child selector pattern

[data-md-color-scheme="slate"] {
  /* variables go in here*/
}

[data-md-color-scheme="slate"] strong, [data-md-color-scheme="slate"] .md-nav__title, [data-md-color-scheme="slate"] h2, [data-md-color-scheme="slate"] h3, [data-md-color-scheme="slate"] h4 {
  color: rgba(255, 255, 255, 0.87);
}
