The red LEDs stimulate Chlorophyll A and B production which is necessary for zooxanthellae growth and health.
Most corals feed on algae produced by sunlight and often called photosynthetic algae or zooxanthellae.
The change of color may be caused by an increase of zooxanthellae or that more zooxanthellae algae are visible in the absence of the UV reflective pigments.
For zooxanthellae in your coral's tissue, the light peaking at 450nm will have
Taking a reef aquarium as an example, the Zooxanthellae that live in coral tissues depend heavily on specific types of light energy to flourish in a symbiotic relationship with the host coral.
are known to host different Symbiodinium species throughout the year- zooxanthellae with tolerance of higher light(and heat) tolerances can be prevalent during the summer months.
Their zooxanthellae will be at a maximum rate of photosynthesis early in the morning, and their natural protective devices(the Xanthophyll Cycle) comes into play during mid-morning and protects them until light intensity drops in the late afternoon(assuming it
So, what do corals need? In this article from Advanced Aquarist, Dana Riddle shows us that the zooxanthellae algaes in coral respond to different wavelengths with higher rates of absorption and thus produce more food for corals.

For zooxanthellae in your coral's tissue, the light peaking at 450nm will have
B which further benefits the Zooxanthellae that corals depend on to live and grow.
Can we replicate this amount of light in an aquarium? We probably don't want to since a PPFD value is above the Saturation Point of many zooxanthellae species/clades.
Early research on Tridacna crocea, T. gigas, and T. squamosa found them to contain zooxanthellae described as simply Clade A(today, this might be found to be Clade A1.).
So, what does this tell us? If we assume that few Tridacna clams are imported from Japan and that most are from the Indo-Pacific, those specimens in the aquarium trade contain zooxanthellae of Clades A and C(with the possibility of another, Clade D. Clade D is generally assumed to be an opportunistic clade that exploits stressed environments.).
The corals and the Zooxanthellae have difficulty in adapting to this fast changing climate.
Bleaching is the loss of zooxanthellae and/or photo pigments, NOT the loss of coral tissue.
The Zooxanthellae are also what determine more than 90% of a coral's color.
It is the loss of zooxanthellae and/or(photo)pigments.
The corals and the zooxanthellae have trouble with adapting to this fast changing climate.
This change in color actually comes from the Zooxanthellae which reside in the coral.
