thats what i was thinking from my biology days
the color that we see is the color that is not being absorbed or is being reflected
green plants use red and blue
and red understandably will not use red but more green/yellow than other green plants
from what im reading blue light will cause plants to grow more compact because the plants can use that spectrum the best
