I scratched my head when you said you worry about dye. You totally lost me when you then said you clean with solvents. With that kind of flawed logic in your argument, I feel safe disregarding anything else you might try to convince me of.
Tim's tubes are red. It's his "thing". Some like it. Some don't. Just like natural fg. Some like that and some don't. If you don't like it, buy something else, or learn how to paint. Don't know what else to say, except this whole thing is a silly argument to have. Especially since Tim has said he'll make whatever color you'd like, as long as you're willing to pay the extra costs for it (so you have a third option).
Good luck Tim!
