Grid Cards - Custom Colors

[shinybrar]

I have the following grid cards implementation,

<div class="grid cards" markdown>
- [:simple-python: __Python API__ <small>for access and automation</small>](#)
- [:simple-gnubash: __CLI__ <small>for terminal users</small>](#)
- [:simple-rocket: __Try it Out__](#)
</div>

I would like to infill the color of the last grid item, i.e. [:simple-rocket: __Try it Out__](#) with a custom color. Is that something that is possible currently?
