Why the colour of the sky is blue in a day and orange at sunset?

It happens because of scattering of light. During the day the blue light is scattered more and the sun has not travelled so far but in the evening the sun has already travelled a great distance and orangish red is scattered more due to its long wavelength.
hope my answer is correct and it helps you!!

It’s because the air molecules “scatter” short-wavelength light, such as blue light, preferentially. Away from the Sun, the sky seems blue because blue light is repeatedly scattered and enters your eyes from all directions.
When the Sun is high in the sky, for example at noon, the scattering of the blue is not enough to significantly effect the colour of the Sun itself.
At sunset the sky near the Sun can often be red or orange, especially if there are a few clouds to reflect the colours. The direct sunlight has to travel through more air when the Sun is low in the sky. That increases the scattering effect and you can see orange and red. Of course the sky away from the Sun still looks blue.
