How can I dye PET (polyethylene terephthalate)?

I'm making some bowls for a gift with PET bottles and I was wondering if there's a way to dye the PET, well an easy way, the homemade kind. I did a little research and basically found out that it can be done industrially with some expensive equipment and industrial heat resistant dyes, I'm thinking of using glass paint, any other suggestions. Thanks in advance.

I know I have dyed a plastic called g10 before, with rit dye. google g-10, It could be similer to pet. I have also dyed nylon with rit dye.

Don't know about dying as such, but I'm having pretty good luck coloring PET with Bic Permanent Markers and reasonable luck with using Sharpie pens.

This Instructables uses Sharpie pens on PET:
"Plastic Bottle "Stained Glass" Candleholder."

And these two use acrylic craft paint:

"Bottle Butterflies!" https://www.instructables.com/id/Bottle_Butterflies/

Hope this helps.
