Been thinking about replacing the current smartphone, as the touchscreen seems to be failing(Screen replacement seems to be not so economic).
Saw different colours being offered. Black, White, Blueish and Greenish colours were common.
Does the external body colour affect the efficiency of the phone? Like, in heat going out or going in? Or the ease of cleaning it? White colours seem to show presence of dust etc?
And are there other places where the colour matters?
I’ve read that white roofs generally have a lower heat gain than other ones(without infrared reflecting paint).
In terms of heat, efficiency etc., the difference would be negligible if it’s even there to begin with.
The only real difference you’d see is dirt build-up, which would be more noticable on lighter colors. This would still occur on darker colors but you wouldn’t see it as easily.
True.
Have you noted any places where colour would matter?
It matters for growing plants. White containers will draw less heat.
Anything that is in the sun. A white car will not heat up as quick as a black one when you drive in the summer, same for a light colored roof on a house, or a train or a bus.
So whenever something is outside and facing the sun, choose the lighter colored version.
