Red light
Explanation
Red light has the longest wavelength among the colours of visible light. According to Rayleigh’s law, the intensity of scattering is inversely proportional to the fourth power of wavelength:
Scattering ∝ \frac{1}{\text{λ}^4}
Therefore, red light undergoes the minimum scattering.
