Change color of Trigger Text

Place the following in your child theme via:
quick css feature (if available)
style.css
or directly in the plugins custom CSS section under the plugin settings:

CSS:

.collapseomatic {
   color: #027353;
}

color property

Thanks for the quick reply. That does, of course, change the color of the trigger to #027353, but now the visited link is also that color. I have the following in my Collapse-o-matic Custom Style box:

.colomat-visited {
color: #014034;

.collapseomatic {
color: #027353;
}

Any suggestions? Thanks.
(Also is there a list of CSS classes that Collapse-o-matic uses?)

.collapseomatic {
    color: #027353;
}

.collapseomatic.colomat-visited {
    color: #014034;
}

Great, thank you. Thank you for the link as well.
