Went to Carlisle to see some GY3 Curious yellow cars….

I am in NO way a paint guy, but i remember seeing a thread on gy3 that said it was a very difficult paint to match, and there were shade variations all over the place.
I remember seeing that a guy had painted three gy3 coupons with three different brands of paint. I couldn't see any difference on my phone, but apparently he could. I dont remember which he said was closest.
