They say there is no dumb question so here we go. In regards to reverse painting would using regular indoor house paint be bad? Is acrylic model paint better?

The most important considerations are a) colour , b) opacity , c) drying speed

I use an acrylic paint. I am probably not supposed to do this, but I paint the blank, wait 20 minutes or so then epoxy in the tube. The pain mixes with the epoxy but so far it hasn't affected the integrity of the epoxy. I do this instead of coloring the epoxy because it ensures more even coverage of the inside of the blank.

I use the acrylic paint from Michael's that they have on sale often for a dollar or less for a bottle. It will dry in about 20 minutes if you blow air into the blank. I set in on a dehumidifier that runs in the shop and use 5 minute epoxy with a drop of the same paint mixed in to glue the tube in. If the blank is really translucent I also spray paint the tube with Krylon acrylic spray paint that also dries in 20 minutes.

I would add one more to Wayne's list:
d) paint thickness. Some house paints form pretty thick films which might not leave you enough room in the blank to insert the tube. Water based (acrylic / latex) paints would likely be a better choice than an oil based paint (alklyd).
