No.
The literature doesn't not show a correlation between the presence and
intensity of light.
Why would cactus be green and tropical understory plants be red?
As Karen and I are trying to point out here, Why would Red needle leaf
ludwigia, L repens, Rotala's, Ammannia's etc, all be green above the water
where light is higher and red underwater? In both sunlight or in artificial
lighting? UV-A , UV-B can quickly be ruled out here.
The only thing antho's seem good for is anti fungal properties with leaf
cutter ants.
The other stuff does not seem valid.
