When I place a blue ceramic mug or blue ceramic bowl in the microwave, the ceramic seems to heat up hotter than other colours - and the food/drink inside seems to heat up less. Why is it so?

I don't think I've noticed it, but is it possible that Cobalt Blue which contains cobalt and aluminum oxides would be reactive in the microwave?
