@MsKathleen the visible electromagnetic spectrum, you?
The most important perceptions work from within, if you’re intuitive, non intuitive people don’t have those perceptions. Where the non intuitive draws conclusions from direct observations the intuitive will gather way too much information then automatically “jump” to the correct answer and retrace the solution as if it’s news to them.
It’s hard to explain real intuition, the kind that isn’t woo based, but it’s real.
