Does the colour of an appliance like smartphones matter in the aspect of efficiency or use? (lemmy.sdf.org)

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).

True.
Have you noted any places where colour would matter?

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.

It matters for growing plants. White containers will draw less heat.
