Somewhat depends. If issue exists when IH is not installed then there's something else about. Otherwise I expect either removal of the extra IH files for color box or removal of the database settings for color box to correct. Understand though also this plug-in has it's install process where the admin files include installation.

So would need to remove the install files or rename their extension and then do the database removal to prevent reinstallation. FWIW, I'm not currently looking at the package to suggest more guidance, working from memory.
