Red illumination of a Balanus amphitrite photoreceptor that has been adapted to blue light leads to prolonged depolarization in the late receptor potential. This depolarization can be switched off by further exposure to a blue stimulus. The early receptor potential in this cell is purely depolarizing or largely hyperpolarizing; the former is true if the cell has been adapted to red light, and the latter, if blue light has been used. The color-adaptation "memories" for both early and late receptor potentials appear to be permanent. The existence of two stable states for the early receptor potential directly implies a pigment with two stable states, and these apparently contribute antagonistically to the late receptor potential.
对已适应蓝光的藤壶光感受器进行红光照射，会导致晚期感受器电位出现延长的去极化。通过进一步暴露于蓝色刺激可关闭这种去极化。该细胞的早期感受器电位要么纯粹是去极化的，要么主要是超极化的；如果细胞已适应红光，则前者成立，如果使用的是蓝光，则后者成立。早期和晚期感受器电位的颜色适应“记忆”似乎是永久性的。早期感受器电位存在两种稳定状态，这直接意味着色素存在两种稳定状态，而且这些状态显然对晚期感受器电位产生拮抗作用。
