Do these bleed through on Bible pages?

I don't know the answer to that, but I wouldn't even TRY them in my bible (and I'm a Bible journaler!). I use prismacolor colored pencils in all my Bibles.

Where can I buy refills for this pen?

You should be able to purchase refills here on Amazon

Can you right on a rock with these?

I have not tried to do so, and I really doubt that fine of tip would work very well. I guess I would experiment to see if you could. They do make pens especially for writing and painting on rock. I would recommend that type of pen, but try these to see.

Has anyone colored with these?

My uni ball Signo RT1 collection of color gel pens are of 0.28 mm fineness. They are very very fine point. At such fine point, I think you can only write with it. I think it will be hard to color anything with it.
