Solar radiation not a pure yellow light but covers broad range of wavelength that gives white light .

We get solar radiation through atmosphere. Energy absorbed and reradiated by atmosphere depends on fourth power of wavelength .
Hence reradiated light has maximum at shorter wavelength , i.e. more intense in blue region of visible light than red region .
We see this reradiated light , hence if we look up sky, blue radiation is dominant.

At sunset , sunlight is coming in at tangent to earth's surface ant it pass through longer stretch of atmosphere.

Hence much of the blue light is scattered out from our view, only red color light is left out .
Hence we see red color at the time of sunset .
