Existing structural coloration methods using thin films, commonly implemented in high‐purity aluminium, produce colours which are highly dependent on the viewing angle because of the inherent angular dependence of thin film interference. Adapting the thin film coloration mechanism to anodisation of industrial‐quality aluminium alloys, which scatter light more efficiently than their high‐purity counterparts, reduces angle dependence in the colour produced. This reduction of angle dependence, as well as the wide use of anodised aluminium in consumer products, suggests that structural colour based on anodised aluminium could potentially be scaled up for commercial scale production.

降低工业铝平台上结构着色的角度敏感性

现有的使用薄膜的结构着色方法（通常在高纯度铝中实现）会产生颜色，该颜色高度依赖于视角，这是由于薄膜干涉的固有角度依赖性所致。使薄膜着色机制适应工业级铝合金的阳极氧化工艺，可以比高纯度铝合金更有效地散射光，从而降低了所产生颜色的角度依赖性。角度依赖性的降低以及阳极氧化铝在消费产品中的广泛使用，表明基于阳极氧化铝的结构颜色可以潜在地扩大规模，以进行商业规模生产。
