It's not a bug. iBooks is specifically overriding color settings in order to have night mode. That's the way it's written. So it's still not a bug. You go into night mode and your colors are overridden. So what you want to do is something iBooks doesn't do because it was programmed to override.
So what you are asking for is a feature request. It's not a bug.
