I figured out this code to change the text -
 

.qa-like-link.is-active .post__action-link__text {
  color: #692E53;
}

I code not figure out the code to change the like icon though.

Hi ​@ahamburg9 - yes this can be done using custom CSS.  I’m unfortunately not a developer myself, and I don’t want to subject you to my high-risk GPT-fueld coding adventures.  I do believe you’re looking for the element: .icon--thumb-up.  Do you have access to a front-end developer?  Otherwise, perhaps someone else here will chime in.

Thanks for the assist.

Here is what I came up with!

On the main home page

.thread-meta-item--likes--liked .qa-topic-meta-likes-content {
  color: #F3AB39 !important;
}

.thread-meta-item--likes--liked .icon--thumb-up {
  color: #F3AB39 !important; /* Your custom color */
}

Not on the main page within articles, questions, etc.

.qa-like-link.is-active .post__action-link__text {
  color: #F3AB39;
}

.qa-like-link.icon--thumb-up.is-active::before {
  color: #F3AB39 !important;
}

Use at your own caution :)

Awesome stuff ​@ahamburg9 !
