Oxidized IPA

I brewed this about 5-6 weeks ago. It was my first time using Phantasm powder and Helio Gazer yeast. I haven't been drinking beer much lately (weight loss thing) but I poured a pint last night - even outside in the dark, the color didn't look right. I just pulled another glass and it has a weird brownish/gray color while it was originally a pale straw color. I don't know how I introduced oxygen - it was a low pressure fermentation followed by a closed transfer into a pressurized keg. It still tastes pretty good but I assume I will start losing hoppiness shortly. Weird AF!
