It iw due to atmospheric refraction as the RED light has maximum wavelength so it refracts very much

Sunlight contains seven colours. if we are splitting the sunlight using a concave lens, we will get the seven colours of Violet, Indigo, Blue, Green, Yellow, Orange and Red(VIBGYOR - in the ascending order of wavelength), as they are appearing in the rainbow. Out of these colours, Violet colour has the lowest wavelength and Red colour has the highest wavelength.
In the morning and the in sunset, the sunlight has to travel more distance through the atmosphere of the earth for reaching us. So, as the sunlight is travelling more distance through the atmosphere of the earth, only the colours having high wavelength can reach us and colours having low wavelength are missing in the midway because they are scattered easily as the atmosphere of the earth contains air, moisture, smoke and other dust particles.
