Terminal phase adult male bluehead wrasse show rapid and frequent changes of body colour from bright green to opalescent. Green body colour is associated with aggressive chases of other fish, opalescent with courting females and spawning and so the body colour gives an indication of the fish's 'intention' over the next few seconds. Pectoral fin spots appear during courtship and a hypothesis is suggested for their function.
成年雄性蓝头濑鱼在末期阶段会迅速且频繁地改变体色，从亮绿色变为乳白色。绿色体色与对其他鱼类的攻击性追逐有关，乳白色则与向雌鱼求爱和产卵有关，因此体色能表明该鱼在接下来几秒内的“意图”。求偶期间胸鳍上会出现斑点，并针对其功能提出了一种假说。
