I'm using this plugin: http://mods.mybb.com/view/advanced-secure-spoiler

and the spoiler is green, which does not match my forum theme. how do i change the color of the spoiler?

In your forum's root installation, go into inc/languages/(your forum language)/advspoiler.lang.php and find the hex web color "#72B73A" (there should be two), replace it with your new desired color.

If you need a hex color use Color Picker.
