Reef fishes present the observer with the most diverse and stunning assemblage of animal colours anywhere on earth. The functions of some of these colours and their combinations are examined using new non-subjective spectrophotometric measurements of the colours of fishes and their habitat. Conclusions reached are as follows: (i) the spectra of colours in high spatial frequency patterns are often well designed to be very conspicuous to a colour vision system at close range but well camouflaged at a distance; (ii) blue and yellow, the most frequently used colours in reef fishes, may be good for camouflage or communication depending on the background they are viewed against; and (iii) reef fishes use a combination of colour and behaviour to regulate their conspicuousness and crypsis.
珊瑚礁鱼类向观察者展现出地球上最为多样且令人惊叹的动物色彩组合。通过对鱼类及其栖息地颜色进行新的非主观分光光度测量，研究了其中一些颜色及其组合的功能。得出的结论如下：（i）高空间频率图案中的颜色光谱通常设计得在近距离时对色觉系统非常显眼，但在远距离时则具有良好的伪装效果；（ii）蓝色和黄色是珊瑚礁鱼类最常用的颜色，根据它们所呈现的背景，可能有利于伪装或交流；（iii）珊瑚礁鱼类利用颜色和行为的组合来调节自身的显眼程度和隐蔽性。
