Yes, it's possible. If you need to change the background color, you can use one of our colors classes If you want to change the border color, you can add ex. `.bq-info` class to your blockquote. Instead of "info", you can use "danger", "warning", "success" od "primary". If you don't like these colors, you can use CSS to customize the color of the blockquote. Example:

.blockquote {
  border-left-color: #6200ea;
}
