I love old farm logos and cattlebrands. My grandfather who owned a farm when I was a kid always had logos with this mustard yellow and dark blue color, which can also allude to the ag industry. Blue for the dairy and yellow for the corn.
I imagined this on the side of an old pickup truck, embroidered into a shirt or hat, printed on a small notepad and stuck into someone's shirt pocket, or even burnt into the side of a wooden crate. It's simple and harkens back on an older time but still feels new.
