Screen shots on the Kobo Aura H2O original are basically whatever is in the file, so yes they can be in colour.
I'd only use a full spectrum photography lamp reflected off a neutral surface or a grey overcast sky, not near dusk or dawn, to photograph eInk. Also only with light at minimum or off. Bright enough light so that any minimum LED light on Kindle isn't affecting the image. No reflections.
A "screen shot" can't ever show what ANY technology of screen is like as there is the display characteristics (CRT, Plasma, various LCD, OLED, real LEDs, different eink generations etc) as well as software.
It's really difficult because the camera will not have the dynamic range or gamma of your eyes. You need a calibrated screen and adjustment of the photo and even then obvious differences in real life may be much less or distorted compared to the images you view. Colour is even harder than monochrome due to the spectrum/colour rendition as well as colour temperature of lighting (LED and Fluorescent have per model non-continuous spectrums) and also the method of making the camera do colour. Then the backlight colour temperature / spectrum of eventual viewer's display and how that display does colour, the phosphors on OLED or CRT, the dye filters on LCD (all of which age with resulting colour shift). The gamma, contrast, dynamic range, brightness and ambient light of final display.
