Efforts to improve the performance of optogenetic tools for neuroscience research have mostly been focused on mutating the opsin backbones or mining-related algal genomes. Here the authors show that analogues of the chromophore, retinal, can be used for colour tuning of rhodopsins and altering their photocycle kinetics in several model organisms.
