Even on a single Kindle, you can see the effective temperature vary as you move the device into different external lighting conditions. I can flip my Oasis between eerie blue, glowing yellow, no-apparent-backlight-just-looks-white and even (in the right conditions) something that looks somewhat reddish by moving between different levels of ambient light and frontlight intensity.
btw, all those people saying e-ink screens are opaque are not quite right: it is only
practically opaque. I tested this when I broke my old K4 by pulling the screen out and putting a really intense variable theatrical light behind it, because this is what you do when working on lighting and bored. If you turn it way up (and shield the edges with something else so you don't get blinded by the light coming past the edges) you can see that the e-ink is actually somewhat translucent, and does glow if you chuck enough light at the back of it. This is unsurprising because the oil in which the opaque black and white granules are embedded is not itself opaque, so light can still find its way from the back to the front.
(This is not to recommend running a Kindle with a multi-kilowatt theatrical light mounted behind its e-ink layer. It's way too bulky to fit in the case, slow to change light levels, crazily power-inefficient,
really unevenly lit and so hot it nearly melted the screen. I should have got pictures, but I didn't have my camera on me that day.
