That was how I was doing it at first, but I found that it wasn’t taking at all sizes. Once the icon got down below 64x64, it was fuzzy as all get out. So I overwrote the actual ICNS file and had much better results. The info panel trick is great for quick testing, but I’m not sure it’s the best choice for the final placement.
I did try green. I tried every color. But I made it at 6 this morning and figured I should probably trim down the options before my whole Saturday morning got away from me :).
I understand, I didn’t know that.
