It sounds paradoxical, because the idea behind this hypothesis is that the red pigment is made in autumn leaves to protect chlorophyll, the light-absorbing chemical, from too much light.

Breakthrough converts light into energy from plastic strips of film coated with titanium dioxide and light-absorbing dye.

And the use of light-absorbing particles with low thermal conductivity, such as agglomerates of carbon nanoparticles, and carbon coated glass micro-shells.
