Why has the sun in the evening a red colour and in the morning white
or
yellow?

Red colouring is caused by scattering of light by molecules and to some
extent by dust particles. There tends to be more dust and pollen raised
during the day (e.g., car exhausts) so the atmosphere contains more
scattering particles in the evening. Water vapour can also redden
sunlight,
and the water vapour content of the air tends to rise during the day and
drop at night.

Also, it is my own observation that the rising sun is usually about as
red
as when it sets; maybe things are different where you live? Or maybe
you
are not waking up early enough to see the sun actually rise, but you are
staying up late enough to see the sun actually set?

In my area, the Sun is as red at sunset as it is at sunrise as well.

When I looked out the window this morning at the rising sun on the horizon,
it was extremely red, certainly not white or yellow.
