(Steam) Total War: WARHAMMER III from Humble expiring soon

I got an email from Humble the other day saying that some unclaimed keys I've got are expiring sooner than expected, which reminded me to post here. This key for Total War: WARHAMMER III expires at 10am PDT on May 4 (I think that's in about 8 hours from the time of posting?) I've got a few more keys but they've got longer expiries so I'll put them up another day.

I'll send a gift link to the first person to say they want it. To be eligible, you need to include a guess of my favourite colour. Doesn't have to be correct, just want to make sure you're all paying attention.
