Hm, I figured someone would follow up with details... It's been over
20 years since I last tinted a model canopy.

The dye is available at any grocery store, generally near the laundry
detergent. Dave, does that mean you don't frequent that aisle?

I believe best results would be achieved by filling a small pot with
water and mix in a heavy dose of dye. Then immerse the tubing and
heat the water. Bring it up to just starting to think about boiling
and it should be For instrument tubing, I'd use the minimum time and
go for a tint to prevent heat stressing the material.

Don't use the cheap hardware store vinyl - get Tygon.

Needless to say, use an old pot and gloves or tongs.

Dave, if I remember correctly RIT dye is a household product available at
any grocery or drug store. I'm guessing that if you dissolve a bunch in
water and leave it in most any type plastic tube overnight, I'll bet you
can't wash all of it out and you might have what you want. Or maybe dye the
outside too by putting the tube in the pot of dissolved dye overnight. Maybe
heat would help?I'm guessing, I've never done this.

RIT dye works for this. I think Wil Schuemann even
suggested this in one of his articles long ago. Also
works great for model airplane canopies.
