If you are talking about the text, you can see from here:

that it is a deep blue (I choose this color on purpose) and the correct display is that of iPad2: a bright color on bright background: we can define "contrast" the difference of background and foreground.
Obviously the algorithm used by Kindle to convert the color in gray (there are several algorithm) map this blue in a gray more dark respect the blue of the reality. The result can be different on other devices or programs.
Otherwise the JBC map this blue on 4096 color space and it is a more accurate reproduction of the reality (but it is anyway a "map") and so the contrast is more real (while the contrast of Kindle are less real and more "simulated" and computed)
P.s.: iPad2 shows this blue too bright. I think it is a photo defect
