The blue light

Explanation:

Spectrums of visible light with longer wavelength are absorbed more quickly such as red than those with shorter wavelength. This contributes to why blue with higher energy and shorter wavelength is able to penetrate deeply compared to others that are easily absorbed. Blue light persist longer so it reaches the depth first while so of others are absorbed.
