Is the sun setting or rising?

In this photo, I think that 'setting' would be the correct answer for both ideas. Our Republic has never been more divided as orchestrated by a Democratic Party and the mass media. Try typing www.antifa.com and see what the result is....

As to the question of sunrise or sunset - It's a sunset in this case.  Light at sunset is more colorful, and warmer... Why is that so?

Unlike the morning light, evening light is warmer and tends to be more colorful. This again goes back to how light scatters through our atmosphere. Towards late afternoon, there tend to be more (and larger)  particles in our atmosphere in the form of dust and smog from human activities, and water vapor from evaporation throughout the day. These large particles greatly scatter the orange and red light from the sun. As a result, the sky we see above us during sunset is warmer and likely more colorful.

And in contrast to during sunrise, our Earth is rotating away from the sun during sunset. This causes the wavelength of the light to lengthen, causing a Doppler shift towards red light.
