It is my understanding that it isn't a brighter view, just more differentiation. So things that might look smooth and all one colour to some may have shades of colour to a tertrachromat. Eg. Make-up may look splotchy, paint looks streaky, etc. I'm not a tetrachromat, so I don't really know.

Can any tetrachromats weigh in on this?
