This is because the energy of each photon in light is proportional to the wavelength (Energy of a photon = Planck’s constant times wavelength). Blue dyes reflect higher visible wavelengths (not absorb) so are therefore likely to have a minor fade resistance advantage over red and green dyes.

What colors fade fastest in sunlight?
Yellow, orange, and red are the paint colors most susceptible to fading. This is just one reason why paint manufacturers make different types of paint (and colors!) for exterior use.
