如果对影响相关性的参数进行量化，可以更好地理解视觉颜色辨别与色度测量之间的相关性。本文回顾了人类和物理性质的已知参数效应，并提出了基于特征参数效应的色差评估技术的初步修改建议。>p> 人为因素，如观察者之间的可变性，是非常重要的随机因素，可能是不确定性的主要来源。颜色辨别任务呈现中的一些物理变化会导致色差敏感度的显著变化。 在某些情况下，这些变化已被量化，然而，这些结果是使用完全不同的实验技术（例如使用视觉色度计进行颜色匹配或使用物理样本判断恒定刺激）进行的，并且基于非常有限的颜色中心和观察。因此，需要更多的研究来充分了解它们的影响。报告共有18页，1个图表和3个表格。

The variability in correlating visual colour discrimination with colorimetric measures may be understood better if parameters that affect the correlation are quantified. A review is given of known parametric effects of a human and physical nature, and advice is given for a tentative modification of colour-difference evaluation techniques based on characterized parametric effects. >p> Human factors such as variability in and between observers are very important random factors, and may be a major source of uncertainty. Some physical changes in the presentation of colour-discrimination tasks are shown to produce significant shifts of colour-difference sensitivity. In some cases these changes have been quantified, however, these results were carried out using quite different experimental techniques (such as colour matching using a visual colorimeter or judgements of constant stimuli using physical samples) and are based upon very limited numbers of colour centres and observations. Hence, more research is needed for a full understanding of their influence.The report contains 18 pages, 1 figure and 3 tables.
