Colour deficiency or, colloquially, colour blindness, is common and has been observed and described in the scientific literature for ca. 200 years. In more recent times, algorithms have been developed that simulate the effect of colour deficiency to a colour‐normal observer. Sometimes these algorithms are used to indicate potential problems in the colour design, but often the implicit assumption is that a colour‐deficient observer actually sees things that way. But do they? This paper questions some of the underlying assumptions of the algorithms.

颜色不足的观察者如何看待事物。

颜色不足或通俗地说是色盲，这很常见，并且在科学文献中已针对ca进行了观察和描述。200年 在最近的时间里，已经开发出了一些算法，可以模拟色差对正常色彩观察者的影响。有时，这些算法用于指示色彩设计中的潜在问题，但通常隐含的假设是，色彩不足的观察者实际上会以这种方式看到事物。但是，他们呢？本文对算法的一些基本假设提出了质疑。
