Opening Third Eye Experience?

I bought a chakra tuning isochronic which is an upgraded version of a binaural from unexplainable.store. I have been meditating with them for a couple days and with my third eye I can see all kinds of glowy energy when I'm mediating and it looks like there is this hole into the spiritual in the right side of my vision (when my eyes are closed) but it fades when I look directly at it.

And I have had a couple of visions one i brushed my hair while meditating and saw a mirror image at the same time in my minds eye. The other I saw some kind of being all purple outlined in white energy.

So I have two questions. Why when looking through my third eye is everything purple? Is it like that for everyone?

And how long until its fully open roughly I know its probably different for everyone.

Thanks :)

EDIT: and today while doing a heart chakra meditation I felt the sleep paralysis type feeling and it came so close to opening

Iv never heard of the Isocronic thing before, but looked it up and its a set of crystals/stones ?

Anyhow I just think my chakras open, with practice you can open them individually on command.

With the brow chakra you can get external visions as well as internal vision. I see both in full colour, but then Im been meditating for years.

You can usually close chakras if you dont know how by doing something totally mundane like housework, gardening etc. My Chakra stays open while Im working with it, or until I close it.
