Don't know Nip. I have seen some staining in the oil exuded in storage, like your orange in the second picture. Mine didn't turn the bag Orange, just the oil that comes out of the plastic naturally in storage. I notice this occurring far less when I am certain that the color in the bottle has been very well incorporated. I have rinsed the bags with alcohol and they come out clear as when they came from their box after the alcohol dries.
I'm not sure this will help at all, but for my fluorescent orange needs, I add a single drop of tomato to a 4-6 ounce cup and 4-5 drops of the orange. I like the way the tomato makes the color pop. If you look at the tomato closely you'll note the orange in it. Tomato is hyper strong though so a guy really needs to take care if it's going to be used as an adjustment color....it can overwhelm in a blink.
