So, I think, the dark blue will get hotter under the sun...
It depends far more on the reflectivity of the surface than its colour - matt surfaces absorb (and radiate) heat much more efficiently than shiny ones. Very few of us bother to paint our central-heating radiators black, and even if you did, it really wouldn't make that much difference to their efficiency.

Given that the Reader has a somewhat shiny metallic surface, it shouldn't have too much of a problem in sunlight.
