homepage cat colors by category

HI,
I want to change the colors of the category tags in home page, so every cat has a different coloration. How can I do that?

thanks,
m

thanks for the reply but this is not enough for me. I need different colors for each category. I’ve thought a different way to do that: to add the class nicename in the script that displays cats in flex blocks:

<?php if ($category_position == ‘above’) { echo ‘<div class=”‘ . get_cat_name( $cat_id ) . ‘”>’ . $this->get_category() . ‘</div>’; }?>

but I don’t understand why it doesn’t work.

Could you be so kind to give me a hint?

thank’s
m
