Changing colors on cards

[zerothi]

Describe the bug

context
I want to change colors on the full cards similar to the css annotations mentioned for button-link.

expectation
I expected class-card to accept something similar to button-link

bug
But instead nothing happens.

problem
This is a problem for people doing ___ because ___.

Reproduce the bug

I would like an entire card to follow the color schemes that one can choose for button-link.

However, there are no color attributes that associates with the button-link available colors (see here).

So I tried these things:

.. card:: Title
    :class-card: <here>

I tried with bg-primary, sd-color-primary etc. Now, bg-primary actually changes the color.
However, I also have an extra css entry, with:

* {
  --bg-primary: #990000;
}

But it does not use it. Now, I have no idea about css, so probably I am doing things wrong there.

But, ideally, I would like to have a color + highlight color on the card. But I can't get it to work?
Should it work?
