Try suspending your dry hop bag inside the lid and drop it with a string of unwaxed dental floss. Sometimes magnets can be used on plastic fermenters. That way you aren’t opening the lid. Snip the floss and let it drop in.
You need to purge headspace 15 cycles to clear the space, several cycles still has O2 present.
If you cold crash, make sure you aren’t sucking air back into the fermentor as it cools. Some folks use Mylar balloons for this.
If you have to crack the lid open for any reason, hook up a CO2 line to it so you get the gas flow going outward away from your work.
I don’t cold crash IPA’s, I transfer at ambient then chill the keg. Here is a West a coast IPA of mine, no color issues...

Thanks for the suggestions. I did fill the keg with a StarSan solution, let it rest 5 minutes or so, then pushed it all out with CO2 and left keg under pressure before beginning closed transfer. I probably did not purge the head space enough after adding the dry hop addition. Also, thinking about it more, after I dumped the collection jar full of trub (just before dry hopping), I put the collection jar back on, then opened the bottom valve to allow more trub/hop residue to settle there. I normally purge the collection jar of O2 before opening that valve again. This time, I think I forgot to do that, which allowed a huge "burp" of oxygen to go through the beer.
I'm pretty new to kegging my beer, and I have not been filling the keg to the brim (probably more like an inch or so below the gas-in fitting) with my Star San solution because I thought doing so might interfere somehow with the gas-in connector (by having the solution cover it on the inside), so this probably introduced some O2 as well. I dumped out the brown batch and have another NEIPA going now, heading into the keg in another week or so. I'll definitely fill to the brim this time before pushing it out with the CO2. Thanks for the help!
