Currently the card title will use the card body colour for its text. This pull requests lets you set a different card title colour compared to the body, which I find useful especially when using the new CSS variable --#{$prefix}card-title-color.
Personally I prefer this approach versus adding a utility class like text-primary as it allows for greater customisation via the SASS/CSS variables.
If this is useful I can also add a commit for the card subtitle?
