Nowadays in industrialised countries, human beings spend 80–90% of their time indoors. Under these conditions the light, the colours, ie the perceived image, differs considerably from the outdoors. But this also influences the NIF (non‐image‐forming) effects on our nervous system, such as regulation of the circadian rhythm and other physiological effects. The risks to health arising from NIF effects are highlighted. Even though extensive neurophysiological research has demonstrated the importance of proper NIF management for human health, use of the latter is virtually absent in the design practice. Therefore, we highlight the unresolved research challenges which prevent the development of complete models, particularly useful in defining lighting and, above all, colours in indoor environments, to correctly manage NIF effects.

人类的色彩设计和非成像效果：一个未解决的问题

如今，在工业化国家中，人类80％至90％的时间都花在室内。在这些条件下，光线，颜色（即所感知的图像）与室外存在很大差异。但这也会影响NIF（非成像）对神经系统的影响，例如昼夜节律的调节和其他生理影响。强调了NIF效应对健康的危害。尽管广泛的神经生理学研究表明适当的NIF管理对于人类健康很重要，但实际上在设计实践中却没有使用后者。因此，我们着重指出尚未解决的研究挑战，这些挑战阻碍了完整模型的开发，尤其对于定义室内环境的照明以及最重要的是色彩，以正确管理NIF效果特别有用。
