It will depend on the battery of the device and whether it is used with the illumination on or off. As indicated above, having a darker screen means that the illumination of the e-reader is normally used at higher levels, which is compensated for by a more powerful battery. In my particular case (Onyx Boox Tab Mini C) the battery life is similar to the average of my monochrome e-readers (which varies according to their characteristics).
In any case, each user has a different way of using their colour e-readers. Some people use them with the light always off (even if the screen is darker), others use them in a mixed mode (pure text with illumination; images -comics- without illumination, because the colour corrects to some extent the darkness of the screen). I prefer to use the lighting always on (except outdoors). Generalisations should be taken with caution.
