Blue from Soil then into consciousness

I see on the petals of a tiny flower the color of blue, indigo blue or simply deep blue.

Wondering how the color be created, surely the origin is the soil, I conclude, where the flower penetrates into with its powerful roots. Roots often means origine, I think as well.

Flower is said to be evolved from leaves, green leaves then it gives a sensation in human mind thereby triggers the evolution of consciousness.

Creation should be of the nature of our universe.

We can explain the blue which comes from soil with scientific manner by referring to some chemical substances and reactions, bio-mechanism of flower. But nevertheless, so far nobody could give us no clear view of the relation between our consciousness and the color.

Someone said it evokes a feeling of survival due to its association with fruit. But I don’t think so because feeling of beauty often experienced with another thing as well, like geometry.

Anyway, the person who insist on the association with survival would raise a theory that makes proof that geometry as well should be of the sort.

People who have near-death experiences often describe flowers flourishing around but rarely say something of green leaves or lashing fresh greenery like seen in late spring or early summer. (I know only one example: beautiful butterflies flying on the canopy of woods.)
